Low temperature test chamber
发布时间:2020-08-18
Structural features:
The temperature controller of the low temperature test box adopts imported instruments, with PID adjustment, SSR output, fast self-tuning, digital display, and convenient reading.
The working room and the sample rack are made of stainless steel, and the outer box is made of high-quality cold-rolled plate with a beautiful appearance.
The door, working room, and shell are equipped with low-temperature resistant sealing strips and pressing devices to effectively ensure the tightness of the box.
The refrigeration system adopts the French "Taikang" original fully enclosed compressor to ensure the stability of the low temperature test chamber.
It has over-temperature protection and control circuit overload protection, short circuit protection, safe and reliable to use.
