Environmental Stress Screening Chambers,
environmental testing chambers
Rarge water cooled cascade refrigeration system 5184L rapid temp.change chamber
Temperature adaptability test under the condition of rapid change, or gradient for electrical, electronic,
instruments and other products or spare parts, particularly applies to environmental stress screening
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
1. Automatic adding water function, and automatic filling water upon the water short storage while testing.
2.Automatic operation to test process finished, easy to use.
3.Temperature control: LED digital temperature controller can make accurate testing of temperature
setting, control and display.
4. LED digital timer, when the inner box's temperature reached the setting value, then start to time to
ensure the test complete.
5.Accurate pressure: temperature chart always shows the inner box's pressure and relative humidity.
6.Water device is automatically discharge not saturated steam in order to achieve the best steam quality.
7.A integrated silica gel door gasket, air tightness is very good, and long operation life.
8.The inner box is mirror-polished , graceful and non-pollution.

We use PP Film wrapping the test chamber to protect the test chamber from moisture or being scratched
first, then use strong plywood case for easyload and transport, and to keep the chambers from potential
crash or impact.
If you face any problems in future during testing process we promise we will give you a reply within 48
hours and solution provide within 3 working days. We can offer operation video and English operation
muanual. We can provide video-conference. If customers require on-site service, the transport and travel
expense shall be borne by customer.
