High Stability Accuracy Customized Environmental Climatic Test Chambers for PCBA
High Stability Accuracy Customized Environmental Climatic Test Chambers for PCBA
Application:
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 chemical tests;
as environmental conditions for conducting testing of specimens;
Features:
a. High-quality appearance, the body adopted an arc shape, surface automobile coating technology processing, and mechanical explosion-proof handle, easy to operate, safe and reliable.
b. Rectangular multi-layer glass View window, the use of guinea pigs observed in the test window with anti-sweat heaters device prevents water gas condensate, knot, water droplets, LED lamps to keep the inside lighting.
c. Door frame with airtight packing, can be effectively isolated from the internal temperature of the leak
d. With external water supply system, convenient to supplement the cylinder water supply, and automatic recovery using.
e. Compressor cycling system used France “Tecumseh” brand which can effectively remove condenser pipe and between capillary Lubricating oil and whole series adopt environmental protection refrigerant (R23, R404, R507)
f. Controller uses the imported LCD display screen, can display measured values (PV) and setting values (SV) time
g. Controller with multi-segment program editor and temperature and humidity can be fast (QUICK) or slope (SLOP) controlled.
h. Built-in mobile wheels allow easy movement and placed, with a strong positioning screw position.
