4. Product feature:
-- Energy saving: Adopt thermal expansion valve + capillary + cold output of the latest cooling capacity control technology, change the traditional heater offset cooling capacity to control the box temperature. power
loss to achieve energy saving effect (40% energy saving than traditional methods).

--The Internet of Things: environmental test chamber and power supply system are both produced by factory, which can form a LAN to run the environmental test chamber with external PID power supply and environmental monitoring power supply system(It can automatically stop the external PID equipment when the aging equipment fails, reduce the risk of electric shock and protect the sample safety to meet the requirements of the new PID test standard.)
