PID Control High Low Temperature Simulation Environmental Chamber Easy To Operate
Design and development
We have extensive experience in the design and development of non-standard equipment according to the customer's specifications.
Industrial (laboratory) drying ovens, laboratory thermostats, various test climatic chambers, muffle (high-temperature) furnaces can be made according to your dimensions with a wide variety of characteristics and parameters.
It is intended for research and quality control of various materials, products, components, assemblies, structures, mechanisms, measuring instruments, etc. associated with temperature exposure at low temperatures down to -30 ° С and positive up to + 100 ° С and humidity from 10% to 98% at certain temperatures (on request).
It is used to simulate special operating conditions in laboratories of radio-electronic, mechanical engineering, food, chemical, pharmaceutical, etc. industries.
Working Principle
This is so called Fast Shipping Thermal Shock Test Chamber,Thermal Chamber,Thermal Shock Chamber.
Sample is placed in the test chamber, more extreme temperature than test temperature can be set in high-temperature chamber and low-temperature chamber. When it comes to low temperature test, cold chamber door open, and low-temperature chamber working together with test chamber.
When converted into high-temperature test, cold chamber door closed, hot chamber door are opened, and test chamber working together with high-temperature chamber.
Conversion of mechanical action (transferring from high temperature to low temperature or low temperature to high temperature) can be completed in less than 1second, and the temperature can be quickly stabilized. During the whole test, test sample is no need to be moved, and without any human intervention.
