High-Temperature Uniformity 408L Environmental Test Chamber for Electronics 85%R.H 85ºC Testing
1. Application:
Temperature humidity chambers doing 85%R.H. at 85C testing. You can see the new design and testing performance.
2. Features:
The new general design improved several parts:
water and electrical system separate design, outside humidifying, so the electronics components have long service life; the controller is located on the left part of the door, space-saving, much convenient for operation. the electrical control panel is located on the left.
3. Temperature Humidity Test Chamber 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. The door frame with airtight packing can be effectively isolated from the internal temperature of the leak
d. With an 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. The controller uses the imported LCD display screen, can display measured values (PV) and setting values (SV) time
