225L -70℃~150℃ smart high and low temperature and humidity chamber
for lab testing
The temperature and humidity test chamber can accurately simulate
the complex natural environment of low temperature, high
temperature, high humidity, low temperature and low humidity, which
is suitable for the product detection of plastics, electronics,
food, clothing, vehicles, metals, chemicals, building materials and
other industries.
TH-XX-X series depends on different temperature and volume needs.
XX represents the volume of the chamber and it can be
80,120,225,408,504,800 and 1000.
X represents the low temperature of the temp range and it can be A
0℃,B -20℃, C -40℃,D -60℃ and E -70℃.

BOTO product characteristics:
1.The import of compressors and refrigeration accessories by the
well-know brands in the national boundaries ensures the stability
of the refrigeration system.
2.The cause of the faults can be displayed and the reason is easy
to exclude.
3.The special air supply cycle design, the temperature and humidity
distribution uniformity is good.
4.The whole series of imported microcomputer controllers are
colored. Color touch screen, Chinese and English system, can be
used as a function of setting the city value. It can show the cause
of the trouble, exclude easy, super quiet design, effectively
reduce the running noise of the equipment, and
5.Super quiet design, effectively reduce the running noise of the
equipment.
6.Multiple safety protection, refrigerant high voltage protection,
compressor overload protection, current overload protection, over
temperature protection, leakage protection.
