Digital Professional Thermal Shock Chamber With Observation Window
The scientific name of high and low temperature environmental test
box "high and low temperature test box" refers to a test box that
simulates the natural environment. It mainly tests whether the
product is resistant to high and low temperature. To test and
determine the parameters and performance of electrical, electronic
and other products and materials subjected to high temperature, low
temperature, or constant temperature environment changes.

Types of Humidity Systems
There are various types of humidity systems used on test chambers
today such as a water bath, boiler/steam
generator and atomizing system.
Water Pan - Very stable, but slow response
Boiler - Standard on most CSZ chambers. The advantages of this
system are that it can attain 98%
humidity and has large capacity to work in any size unit. The
disadvantages of this system is that live
load from boiler can cause problems at lower temperatures when the
DUT generates heat.
Atomizer - This system sprays very fine drops of water into the
air stream. The advantages of this system
are that it provides good control with live loads. CSZ typically
uses this type of humidity systems for
devices under test that are over 500 watts, with the exception of
larger chambers.
Application :
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
population.
ESS can be performed as part of the manufacturing process or it can
be used in new product qualification testing.
