Air-cooled 150L SUS304 stainless steel temperature and humidity
Temperature and humidity test chamber is also called temperature
testing machine, constant temperature and humidity experimental
chamber, programmable wet heat
alternating test chamber, or constant temperature machine. The
Temperature and humidity test chamber
is used to inspect equipments quality and test performance of
materials in various environments,
and all kinds of materials properties of heat resistance, cold
resistance, dry resistance and
moisture resistance, which is fit for Electronics, electrical
appliances, mobile phones, communications,
meters, vehicles, plastic products, metals, food, chemicals,
building materials, medical, aerospace and
other products quality inspection.
Using the internal pressure box, SUS304# stainless steel tank.
Various protection facilities, configure the wireless remote alarm
Double door sealing structure, adjustable locking mechanism.
The box adopts LCD LCD touch screen, there is trouble to talk menu,
the trouble of the interpretation of
the interpretation of the failure.
The refrigeration compressor and key accessories are all imported
brands.Environmental protection cold media refrigeration, in line
with international environmental
protection convention requirements.
Various optional accessories: rs232/485 communication interface,
record printer, remote temperature
control system (including communication software, computer
