KOMEG Qualitest climatic test equipments for laptop test For
environmental stress testing
An environmental chamber, also called climatic chamber or climate
chamber, is an enclosure used to test the effects of specified
environmental conditions on biological items, industrial products,
materials, and electronic devices and components.
Such a chamber can be used:
as a stand-alone test for environmental effects on test specimens;
as preparation of test specimens for further physical tests or
as environmental conditions for conducting testing of specimens;
● Stainless steel exterior
● Energy-efficient refrigeration with exclusive electronic
expansion valve system
● Specialized humidity generation and control
● Unique thermal break construction for extreme testing
● Sight window*1, cable port(portΦ50mm)*1, shelves*2, chamber
lamp*1, power cable *2m
● No fuse breaker, over pressure,over heat and over current
protection for compressor, Over temperature protection, over load
protect of blower, dry heat protection
A. Reliability testing based on current test standards in the
temperature range of -40 °C to 180 °C and 10% to 98% R.H.
B. The ideal simulation chamber for all heat and cold testing in
the traditional temperature range -40 ºC and 150 ºC.
C. Forced ventilation loops design, balance temperature &
humidity control system (BTHC).
D. We can provide custom-made machine and optional accessories
satisfied your special requirements.
E. Improved programming and data collection via computer
F. Energy-saving operation, the KM-5166 controller uses advanced
control of an electronic expansion valve to save energy and improve
control of the refrigeration system. Improvements in refrigeration
and heater operation make the new generation of KOMEG environmental
test chambers the most energy efficient ever.
●Cable Port: Φ100mm cable port is available
●Ro-type water purifier:R-80/day
Provide to keep the humidifying heater and wet bulb wick free from
●Inner glass door with operation port
A glass door can be provided behind the main door so that specimens
can be observed. Two operation ports of 130mm diameter are used for
handing specimens inside the chamber without opening the glass
The rotation regenerating dehumidifier M-120 ensures precise
control of low humidity (5℃ 5%RH) for electrostatic reliability
●Temperature and humidity recorder
Temperature 1 pen and humidity 1 pen.
Temperature 3 dots and humidity 1 dot.
Temperature 6 dots and humidity 6 dots.
The chamber automatically detects and melts the frost on the
evaporator when operating below 0℃.
●Liquid or infection
In order to rapidly decrease the temperature inside the chamber, a
cylinder of liquid can be connected the chamber
