Programmable Cold Hot Temperature Cycling Chamber
Thermal Shock Test Equipment
Brief Introduction:
Thermal Shock Test Chamber is used to test the bearing extent of
the material structures and composite material in an instant and
continuous high temperature and extremely low temperature
environment, which is in the shortest time to test its thermal
expansion and contraction caused by chemical change or physical
harm.
QTS3 series air-to-air thermal shock chambers circulate cold, hot,
or ambient air as needed. The conditioned air is pre-cooled or
pre-heated beyond the set point, allowing quicker recovery of the
desired condition after transfer.
The equipment is widely used in metal, plastic, rubber, electronics
and other materials and it can be used as an important reference
for improving product quality. It meets the standard of MTL, IEC,
JIS, GJB…
QTS3 Features:
1. Automatically setting of pro-cooled and pre-heated air.
2. Testing samples don’t move, cable port is available for power on
testing.
3. Powerful interactive touch screen controller, easy operation and
setting
4. High accurate temperature recovery with PID auto tuning
5. Auto defrost function
6. System alarms are stored in memory for historical review
7. Operation data can be downloaded as needed,with RS-232C
communication port for connecting PC to control, record and save
test report.
8. Cold and hot shock temperature recover within 5 minutes, which
complies with MTL, IEC, JIS, GJB and other international standards.
