56L High Accuracy Hot And Cold Impact Temperature Thermal Shock
Test Chamber For Rubber
Brief Introduction:
The iqualitrol Programmable Three Zones Thermal Shock Test Chamber
is applied to aviation, military, ships, electrical, electronics,
instruments and meters; medical equipment; civilian nuclear energy;
colleges and universities; research laboratories; commodity
inspection, arbitration, and technical supervision departments;
building materials ceramic; petroleum and chemical products, For
high and low temperature impact test.
High memory capacity,can set 120 programs and each program can be
repeated for max 9999 times.Each step can be proceeded for max 999
hours and 59 minutes.It's able to communicated with computer via
RS485 port,so as to control,edit and record 2 groups of dynamic
nodes,easy to operate.
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.
QTS3 Features:
Automatically setting of pro-cooled and pre-heated air.
Testing samples don’t move, cable port is available for power on
testing.
Powerful interactive touch screen controller, easy operation and
setting
High accurate temperature recovery with PID auto tuning
Auto defrost function
System alarms are stored in memory for historical review
Operation data can be downloaded as needed, or continually, to USB.
