Stable Lead Time ESS Test Chamber Thermal Cycling Chamber for PV
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 test (ESS)
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
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.

Customized sizes and configurations available
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.
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.
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.
