B. STRUCTURE
1.The outer skin is make of steel plate coating with Zinc on double sides, processed with digital controll, and painting precess on surface for protection.
2.The inner material is stainless steel SUS304.
3.The chamber is divided into 3 parts: high temperature zone, low temperature zone and testing zone. Special heat isolating structure and preserve cold and heat treatment.
4.Lead high or low temperature into chamber by switching over cold or heat air valve.
5.Can set low, high,or thermal shock model independently, two cases or three cases option at thermal shock model, meanwhile,high and low temperature testing function is available.
6.Switching over time for wind direction valve is less than 10 seconds.
C. CONTROLLER
1.Originally Japanese computer LCD displayer (320*240 Dots), bilingual of Chinese and English, simple and easy to operate.
2.RS232 communication interface, programme with computer to operate,collect data and record.
3.Full-automatic high-accuracy system circuit, high accuracy in temperature control.
4.PLC control, PID automatic calculate.
5.In case of unusual condition, the screen display alerm, and stop operation.
