TH160EX-E Wall-Mounted Intrinsically Safe Explosion-Proof Temperature and Humidity Transmitter

Biopharmaceutical clean rooms, laboratories or other high-standard spaces require strict control of temperature and humidity; However, the dangerous and explosive volatile gases may be produced in some areas, so the temperature and humidity sensor needs to have explosion-proof function.

TH160EX-E adopts the wall-mounted structure of dust-proof and ash-proof, which is specifically used for the temperature and humidity monitoring of the explosive and hazardous gas environment in the biopharmaceutical clean rooms. The signal cable is connected through the external terminal to facilitate equipment maintenance.

For the biopharmaceutical clean room O3 or VHP sterile environment, the probe can be equipped with VHP filter PF04, which micropores are filled with the MnO2 composite catalyst with the particle diameter of about 10um; When in touch with the filter, VHP or O3 will be decomposed into H2O and O2 to achieve the purpose of protecting the probe and humidity-sensitive element.
