The purpose of the standard constant temperature and humidity chamber: (PCB/FPC industry-specific) is to simulate the product under the combination of temperature and humidity in the climatic environment (high and low temperature operation & storage, temperature cycle, high temperature and high humidity, low temperature and low humidity, condensation test.. , etc.), to detect whether the adaptability and characteristics of the product itself have changed. ※ It is required to meet the requirements of international standards (IEC, JIS, GB, MIL...) to achieve international measurement procedure consistency (including test procedures, conditions, methods)

Refrigeration advantages
Low-temperature control mode of traditional equipment: cooling compressor start-stop control temperature (large temperature fluctuation, seriously affecting compressor life, technology that has been eliminated) constant operation of refrigeration compressor + heating PID control (causing cooling capacity and heating phase offset to achieve temperature dynamic balance Waste a lot of power) New PWM cold control technology to achieve low-temperature energy-saving operation: low-temperature working state, the heater does not participate in the work, control the refrigerant flow and flow direction of the refrigeration unit through PWM technology, to the refrigeration pipeline, cold bypass pipeline, heat The three-way flow adjustment of the bypass pipe enables automatic constant temperature to the working chamber. This method can reduce energy consumption by 40% under low temperature conditions.
