TH230 Harsh Industrial Grade Multi-Parameter Temperature and Humidity Transmitter

In the extreme high and low temperature and high humidity environment, humidity measurement faces great challenges. The core device of TH230 adopts PT1000 temperature-sensitive resistor and high molecular humidity-sensitive capacitor that can withstand the extreme high and low temperature and high humidity environment. The working measurement temperature can be up to -40~190℃. At the same time, the parasitic parameters of the signal cable are compensated by algorithm, and the maximum 20m signal cable can also ensure high precision measurement.

TH230 can output not only temperature and relative humidity, but also dew point, frost point, wet bulb temperature, enthalpy value, partial pressure of water vapor, mixing ratio, absolute humidity, water activity, dissolved water content in oil and other humidity parameters. In addition, the TH230 can also have field display with the display content customizable by the user, and two ways of temperature and humidity parameters can be displayed.
