~The High and Low Temperature (*-Zone) Thermal Shock Test Chamber
consists of high temperature zone (preheat zone), low temperature
zone (precool zone) and test zone (room temperature zone) with
independent air flow switches which can lead the air inside the low
or high or room temperature zone to the test zone, which makes the
testing samples rapidly undergoing three zones’ temperature by
turn. The samples are immobile during the whole test. This kind of
test chambers is designed to test the reliabilities to rapid-rate
temperature change of a complete product, machine components and
parts and materials. It can test the samples’ chemical changes or
physical damages aroused by thermal expansion in the shortest time,
and also know of the effects on the samples under one or several
times of tests with rapid-rate temperature change.
