The ideal test tool for sexual change.

Why choose excellent instruments and technical features;

(1). With disk USB recording function, no need for recorder;

(2). Refrigerant servo valve flow calculation control. Power saving 30%;

(3). High temperature and high humidity test to prevent condensation and dripping technology

(4). Low temperature working state, the heater does not participate in the work, the refrigerant flow and flow direction of the refrigeration unit are controlled by PWM technology, and the three-way flow regulation of the refrigeration pipeline, the cold bypass pipeline and the hot bypass pipeline is realized to realize the temperature of the working chamber. Automatically constant. This method can reduce energy consumption by 40% under low temperature conditions.

(5) Temperature synchronous lifting slope control (IEC68-2-56, 68-2-30), no dripping, no condensation.

(6) Advantages of refrigeration: Low-temperature control mode of traditional equipment: Ø The temperature of the refrigeration compressor starts and stops is controlled (the temperature fluctuation is large, which seriously affects the life of the compressor.

Technology that has been eliminated) Ø Constant operation of refrigeration compressor + heating PID control (causing refrigeration and heating to cancel the temperature dynamic balance

Waste a lot of power) • New PWM cold control technology for low-temperature energy-saving operation: new PWM cold control technology for low-temperature energy-saving operation

Temperature shock test box control method:

Use low temperature and high temperature cold storage energy storage tanks, open DAMPER according to the action, introduce the cold and hot energy in the storage tank into the test tank to achieve rapid temperature impact effect, balance temperature control system (BTC) + special design air circulation cycle The system controls the SSR in a dynamic PID mode, so that the heating amount of the system is equal to the amount of heat loss, so it can be used stably for a long time.
