Features:
1. High-texture appearance, the surface handled through the matte stripes, and use of planar non-reactive handles, easy to operate, safe and reliable.
2. Rectangular complex glass window can be viewed the testing sample, windows with anti-sweat heater device that prevents water vapor condensation, and high-brightness PL light.
3. Double-insulated airtight container, which can effectively isolate the internal temperature of leakage.
4. With an external water supply system can be easy to supply water and automatically reuse. 5. Compressor circulatory system from French "Taikang", more effective removal of oil between the condenser and the capillary and use environmentally refrigerants (R23, R404, R507).
6. Controller imported LCD display screen can be displayed measuring values and setting the value and time.
7. Controller with multi-segment program edited, temperature and humidity can be controlled quickly (OUICK) or slope (SLOP).
8. Built-in mobile pulley easy to move and has a strong positioning screw fixed position.If you need more models about our test equipment, please reference our chamber-testing（.）com
Control:
English LCD display LCD touch-panel, the screen on the input data, and programmable temperature and humidity, backlight adjustable 17, curve, curve of setting/display value. Can display a variety of alerts, failure occurs through the screen display, eliminating failures, eliminate misuse. Multi-PID control functions, sophisticated monitoring functions, and the data displayed on the screen.

Application :
Environmental stress screening (ESS) refers to the process of exposing a newly manufactured or repaired product or component (typically electronic) to stresses such as thermal cycling and vibration in order to force latent defects to manifest themselves by permanent or catastrophic failure during the screening process. The surviving population, upon completion of screening, can be assumed to have a higher reliability than a similar unscreened population.
ESS can be performed as part of the manufacturing process or it can be used in new product qualification testing.
ESS Testing Purpose:
Testing at the physical environmental conditions (shock, vibration, temperature, altitude, humidity, etc.) that simulate those encountered over the operational life of the component. Random vibration and temperature cycling have proven to be the most successful forms of ESS in terms of effective flaw precipitation.
