The high and low temperature aging test chamber is a device used to simulate high and low temperature environments and conduct reliability testing on products. It is widely used in multiple industries such as electronics, automotive, aerospace, etc. The high and low temperature aging test chamber simulates high and low temperature environments to test the performance stability of products or materials under high temperature, low temperature, and temperature cycling conditions.
Working Principle:
Heating system: Using electric heating tubes or nickel chromium alloy heaters, accurate temperature rise is achieved through PID control.
Refrigeration system: relying on components such as compressor, condenser, evaporator, etc., using refrigerant circulation to achieve cooling.
Circulating air path: By using multi blade fans to force air circulation, the temperature inside the box is ensured to be uniform (within ± 2 ℃), avoiding blind spots during testing.
Control System: Imported microcomputer integrated controller, supporting 120 sets of programs and 12000 step settings, capable of real-time monitoring of temperature curves and automatic correction of deviations.
Performance Characteristics
Wide temperature range: The temperature range is usually -70 ℃ to 150 ℃, and some products can reach lower or higher temperatures to meet the testing needs of different products.
High control accuracy: The temperature fluctuation is generally ≤± 0.5 ℃, and the temperature uniformity is ≤ 2 ℃, which can provide a stable and accurate testing environment for the product.
Multiple protection measures: equipped with various safety protection devices such as fan overload protection, compressor overheating protection, overpressure protection, and overtemperature protection to ensure the safety of equipment and samples.
Data recording and analysis: Some devices have data storage functions that can record temperature change data, making it convenient for users to conduct data analysis.
maintenance
Daily cleaning: Regularly clean the dust inside the box to avoid affecting the air circulation; The condenser is cleaned once a year to ensure heat dissipation efficiency.
Sealing inspection: Check the sealing of door seals and observation windows every month to prevent temperature fluctuations caused by air leakage.
Calibration service: The temperature sensor is calibrated annually by the team to ensure data accuracy.
Long term shutdown: Power on for 1 hour every half month to prevent the compressor lubricating oil from solidifying; The waterway system needs to be emptied to avoid scaling.
