TH160EX Industrial Grade Intrinsically Safe Explosion-Proof Multi-Parameter Temperature and Humidity Transmitter

The clean rooms, laboratories or other high-standard spaces in the field of fine industry 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 is specially used for the temperature and humidity measurement in explosive and hazardous gas environments. In addition to temperature and humidity parameters, it can also measure other humidity parameters such as dew point, frost point, enthalpy value. Especially 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.
