   This series of low-temperature chamber for low temperature industrial product reliability test. Performance indicators in line GB/T5170.2; GB2423.1-1989. Low temperature test methods indicators: GB/T2423 2-1989; temperature change test methods: "Electrical and electronic products the basic parameters of environmental testing equipment, test methods" requirement. Mainly used in metal materials, aerospace, quality research, universities and other industries.
Cabinet structural features
  Cryostat box with CNC machining, nice shape, and no reaction handle, easy to operate.
Imports of high grade stainless steel inner tank (SUS304) mirror panels, cabinet outside the gall A3 steel spray, increasing the appearance of texture and cleanliness.
Large observation window with bright lights to keep the box, and the use of heating element embedded glass, clear observation box at any condition.
   Cryostat temperature control using the full import of the key instruments, simple operation settings.
After the input data and test conditions, the controller has a locking function to avoid human touch and change the temperature.
Optional printer.
Refrigeration and air duct circulatory system
  Double glass reactor tube reel: vacuum insulation layer may be, within the reactor temperature by decay heat exchange coil heating and cooling heating and cooling
Double insulation jacket glass reactor with: insulation sleeve insulation, windows with translucent may (or vacuum can be put inside the cellular calcium chloride anhydrous, low on the window glass surface without frosting), mezzanine cooling through oil heating up lower the temperature
Three glass reactor: The outer glass processing high vacuum insulation, laminated pass oil heating refrigeration or cooling, using powerful multi-wing air circulation blower, to avoid any dead ends, make uniform temperature distribution within the test area. Air duct return air circulation design of wind, air pressure, wind speed meet testing standards, and can open the door fast instantaneous temperature stabilization time.
Standards compliant
