• Got Your Temperature Test Chamber? Here’s What You Must Do Next!

  Nov 28, 2025

  I. Receipt Inspection  1. Physical Verification Confirm equipment model, specifications, and serial number match the contract/packing list to avoid wrong delivery. Inspect the cabinet, door, and control panel for transportation damage (dents, deformation) and ensure pipelines/wiring are intact without loosening. 2. Accessory & Document Check Required accessories: Power cord, sample shelves, sealing rings, wrenches, and other tools (verify against the packing list). Technical documents: Operation/maintenance manual, calibration certificate, warranty card, and qualification certificate (all mandatory for after-sales service). 3. Abnormal Handling In case of damage or missing items: Immediately take photos (overall equipment, damaged details, packing list), notify the supplier within 24 hours to submit a claim, and sign the "Acceptance Objection Form" for documentation. II. Installation & Deployment (Compliant Installation Ensures Performance) 1. Environment Requirements (Must Meet the Following) Floor: Flat and sturdy, with load-bearing capacity ≥1.2 times the equipment weight (to avoid test errors caused by vibration). Space: ≥30cm ventilation gap around the cabinet; keep away from heat sources, water sources, dust, and strong electromagnetic interference. Power supply: Match the rated voltage (e.g., 380V three-phase five-wire/220V single-phase), grounding resistance ≤4Ω, and equip an independent air switch (power ≥1.2 times the equipment's rated power). Environment: Room temperature 15-35℃, humidity ≤85%RH (no condensation); water-cooled models require pre-connected cooling water circuits meeting specifications. 2. Basic Installation Steps Level the equipment: Adjust anchor bolts and use a level to confirm horizontal alignment (to prevent uneven stress on the refrigeration system). Wiring inspection: Connect the power supply per the manual and ensure correct neutral/grounding connections (a common cause of electrical failures). Consumable check: Confirm refrigerant and lubricating oil (if applicable) are properly filled with no leakage. III. Commissioning (Core: Verify Performance Compliance) 1. First Startup Procedure （1） Recheck power/pipeline connections before power-on; switch on after confirmation. （2）Panel self-test: Ensure the display shows no error codes and buttons/indicators function normally. （3）No-load operation (2-4 hours): Set a common temperature range (e.g., -40℃~85℃) and monitor temperature fluctuation ≤±0.5℃ (meets industrial standards). Check door sealing (no obvious air leakage), operating noise ≤75dB, and normal start/stop of refrigeration/heating systems. 2. Load Verification (Simulate Actual Usage) Place a load equivalent to the test sample (weight/volume ≤80% of the equipment's rated load) without blocking air ducts. Set the target temperature and holding time; record if the heating/cooling rate meets technical parameters (e.g., -40℃~85℃ heating time ≤60 minutes). Alarm test: Simulate power failure, over-temperature, or door-open timeout to confirm timely alarm response (audio-visual alarm + shutdown protection). IV. Emergency Handling & After-Sales Coordination 1. Common Fault Resolution Error codes: Refer to the "Troubleshooting" section in the manual (e.g., E1=Over-temperature, E2=Power abnormality). Sudden failures: (e.g., electric leakage, abnormal noise, refrigeration failure) Immediately cut off power, stop use, and contact the supplier's technical support (do not disassemble independently). 2. After-Sales Support Retain the supplier's after-sales contact (phone + email) and confirm the warranty period (usually 1 year for the whole machine). Maintenance records: Request a "Maintenance Report" after each service and file it for future tracing.

• Key Differences in Using Environmental Test Chambers Between Summer and Winter

  Nov 26, 2025

  The core difference lies in the impact of ambient temperature and humidity variations on equipment operating efficiency, energy consumption, and test accuracy. Targeted measures for temperature/humidity control, heat dissipation/anti-freezing, and maintenance are required. Specific differences and precautions are as follows: I. Core Difference Comparison Table Dimension Summer Operation Characteristics Winter Operation Characteristics Ambient Conditions High temperature & high humidity (room temp: 30-40℃, RH: 60%-90%) Low temperature & low humidity (room temp: 0-15℃, RH: 30%-60%) Equipment Load High refrigeration system load, prone to overload High heating system load; humidification compensation required for certain models (e.g., temperature-humidity chambers) Impact on Test Accuracy High humidity causes condensation, affecting sensor accuracy Low temperature leads to pipeline freezing; low humidity may reduce stability of humidity tests Energy Consumption High refrigeration energy consumption High heating/humidification energy consumption   II. Season-Specific Precautions (1) Summer Operation: Focus on High Temperature/High Humidity/Overload Prevention 1. Ambient Heat Dissipation Management Reserve ≥50cm ventilation space around the chamber; avoid direct sunlight or proximity to heat sources (e.g., workshop ovens, air conditioner outlets). Ensure laboratory air conditioning operates normally, maintaining room temperature at 25-30℃. If room temp exceeds 35℃, install industrial fans or cooling devices to assist heat dissipation and prevent refrigeration system overload protection triggered by high ambient temperatures. 2. Moisture & Condensation Control Regularly clean chamber door gaskets with a dry cloth to prevent sealant aging and air leakage caused by high humidity. After humidity tests, open the chamber door promptly for ventilation and wipe off condensation to avoid moisture damage to sensors (e.g., humidity sensors). 3. Equipment Operation Protection Avoid prolonged continuous operation of extreme low-temperature tests (e.g., below -40℃). Recommend shutting down for 1 hour after 8 hours of operation to protect the compressor. Periodically inspect refrigeration system radiators (condensers) and remove dust/debris (blow with compressed air monthly) to ensure heat dissipation efficiency. (2) Winter Operation: Focus on Anti-Freezing/Low Humidity/Startup Failure Prevention 1. Ambient Temperature Guarantee Maintain laboratory temperature above 5℃ (strictly follow 10℃ if specified as the minimum operating temperature) to prevent pipeline freezing (e.g., refrigeration capillaries, humidification pipes). For unheated laboratories, install an insulation cover (with ventilation holes reserved) or activate the "preheating mode" (if supported) before testing. 2. Humidification System Maintenance Use distilled water in the humidification tank to avoid pipe blockage from impurity crystallization at low temperatures. Drain water from the humidification tank and pipelines during long-term non-use to prevent freezing-induced component damage. 3. Startup & Operation Specifications In low-temperature environments, activate "standby mode" for 30 minutes preheating before setting test parameters to avoid compressor burnout from excessive startup load. If startup fails (e.g., compressor inactivity), check power voltage (prone to instability during winter peak hours) or contact after-sales to inspect pipeline freezing. 4. Low Humidity Compensation For low-humidity tests (e.g., ≤30% RH), winter dryness may cause rapid humidity. Adjust humidification frequency appropriately and use the "humidity calibration" function to reduce fluctuations. III. General Precautions (All Seasons) Calibrate temperature/humidity sensors quarterly to ensure data accuracy. Clean air filters monthly to maintain airflow circulation. Arrange test samples evenly to avoid blocking internal air ducts and ensure temperature/humidity uniformity. For long-term non-use: Run the chamber for 1 hour monthly in summer (moisture prevention) and drain pipeline water in winter (freezing prevention). By addressing seasonal environmental variations, equipment service life can be extended, and test failures caused by temperature/humidity fluctuations avoided—aligning with the high precision and stability requirements of the industrial test equipment industry.

• Differences Between High-Low Temperature Test Chamber and Thermal Shock Chamber

  Nov 26, 2025

  In industrial product reliability testing, high and low temperature test chambers and temperature shock test chambers are core environmental testing equipment, both simulating extreme temperatures to verify product durability. However, they differ fundamentally: the former focuses on gradual temperature-humidity cycles, while the latter on instantaneous thermal shock. Clarifying these differences is key to matching test needs and ensuring data validity. 1. Rate High-Low Temperature Test Chamber: Slow, with a regular rate of 0.7∼1 ℃/min, and rapid versions can reach 5∼15 ℃/min. Thermal Shock Chamber: Abrupt, with instant switching. 2. Structure High-Low Temperature Test Chamber: Single-chamber structure, integrating heating, refrigeration, and humidification functions. Thermal Shock Chamber: Multi-chamber structure, including high-temperature chamber, low-temperature chamber, and test chamber. 3. Temperature Continuity High-Low Temperature Test Chamber: The temperature changes smoothly without any "shock sensation". Thermal Shock Chamber: The temperature changes by leaps and bounds, with a common temperature range of −40∼150℃. 4. Application High-Low Temperature Test Chamber: Suitable for temperature endurance testing of general products such as electronic devices, household appliances, and building materials. Thermal Shock Chamber: Suitable for shock resistance testing of temperature-sensitive products such as automotive electronics, semiconductors, and aerospace components. 5. Core Position & Test Purpose High-Low Temperature Test Chamber: Simulates gradual temperature (and humidity) changes to test product stability under slow thermal variation (e.g., electronic devices’ performance after gradual cooling to -40℃ or heating to 85℃). Thermal Shock Chamber: Simulates abrupt temperature switching (≤30s transition) to test product resistance to extreme thermal shock (e.g., auto parts adapting to drastic day-night temperature changes, aerospace components’ tolerance to sudden high-low temperature shifts). Summary The high and low temperature test chamber is a "slow-paced endurance test", while the temperature shock chamber is a "fast-paced explosive power challenge". Just based on whether the product will encounter "sudden cold and heat" in the actual usage scenario, the precise selection can be made.

  Nov 25, 2025

  The 3-zone thermal shock chamber is a test device for simulating extreme temperature shock environments, composed of a high-temperature chamber, a low-temperature chamber, and a test chamber. I.  Detailed Introduction 1.1 Working Principle The high-temperature chamber achieves precise temperature control via heaters and a PID logic circuit, while the low-temperature chamber maintains low temperatures through a refrigeration system. During testing, the sample stays stationary in the test chamber; the control system switches dampers to rapidly inject high/low-temperature air into the test chamber for thermal shock tests. 1.2 Structural Features Adopting an upper-middle-lower structure (upper: high-temperature; lower: low-temperature; middle: test chamber), its internal/external materials are mostly stainless steel. Insulation materials (superfine glass fiber, polyurethane foam) ensure excellent thermal insulation. A test hole on the left facilitates external power supply and load wiring for component testing. 1.3 Performance Parameters Programmable temperature shock range: typically -40℃ to +150℃; temperature control accuracy: ±0.2℃; chamber uniformity: ±2℃; maximum shock duration: 999h59min; adjustable cycles: 1-999 times. 1.4 Control & Operation Equipped with a large color LCD touch controller (Chinese/English interface), it supports independent setting of multiple test specifications, and features real-time status display and curve visualization. 1.5 Safety Protection Comprehensive protections include power overload, leakage, control circuit overload/short-circuit, compressor, grounding, and over-temperature protection, ensuring reliable long-term operation. II. Main Applications Electronics Industry: Tests performance/reliability of electronic components, PCBs, semiconductors under extreme temperatures to ensure stable operation and reduce after-sales failures. Automotive Industry: Evaluates temperature resistance of auto parts (engine, battery, electronic control system, interior materials) by simulating climatic temperature changes, guaranteeing vehicle performance and safety. Aerospace Field: Tests aerospace electronics, sensors, aero-engine blades, and materials under thermal shock to ensure flight safety. Materials Science: Assesses thermal expansion/contraction and weather resistance of materials, providing data for R&D and application of new materials.

• What should we pay attention to when using a thermal shock test chamber (water-cooled)?

  Nov 22, 2025

  I. Before Operation Use deionized water or distilled water as cooling water (to prevent scale formation); control temperature at 15-30℃, pressure at 0.15-0.3MPa, flow rate ≥5L/min. Clean the Y-type filter element in advance to ensure unobstructed water flow. Inspect water supply/drainage pipelines for secure connections, no leakage or kinking; keep drainage ports unobstructed with a height difference ≥10cm. Ensure the environment is ventilated and dry, grounding resistance ≤4Ω, and power supply (AC380V±10%) stable. Keep the inner chamber and shelves clean. Sample volume ≤1/3 of effective capacity, with weight evenly distributed on shelves. Seal moisture-sensitive parts of non-hermetic samples to avoid condensation affecting test accuracy. II. During Operation Real-time monitor cooling water pressure, flow rate and temperature. Immediately shut down for troubleshooting (pipeline blockage, leakage or chiller failure) if pressure drops sharply, flow is insufficient or temperature exceeds 35℃. Set high/low temperature parameters per GB/T, IEC and other standards (not exceeding rated range); control heating/cooling rate ≤5℃/min. Prohibit instantaneous switching between extreme temperatures. Do not open the door arbitrarily during operation (to prevent scalding/frostbite from hot/cold air). Use protective gloves for emergency sample handling. Shut down immediately for maintenance upon alarm (overtemperature, water shortage, etc.); prohibit forced operation. III. After Test Turn off power and cooling water inlet/outlet valves; drain residual water in pipelines. Clean the water tank and replace water monthly; add special water stabilizer to extend pipeline service life. Wipe the inner chamber and shelves after temperature returns to room temperature. Clean the air filter (1-2 times monthly); inspect pipeline seals and replace aging/leaking ones promptly. For long-term non-use: Power on and run for 30 minutes monthly (including water cooling system circulation), inject anti-rust protection fluid into pipelines, and cover the equipment with a dust cover in a dry, ventilated place. IV. Prohibitions Prohibit using unqualified water (tap water, well water, etc.) or blocking filters/drainage ports (to avoid affecting heat dissipation). Prohibit overloading samples or unauthorized disassembly/modification of water cooling pipelines/core components. Repairs must be performed by professionals. Prohibit frequent start-stop (wait ≥5 minutes after shutdown before restarting). Prohibit placing flammable, explosive or corrosive substances.
