The transmitters measure relative humidity and temperature and from these calculate dewpoint and wet bulb temperature, mixing ratio and absolute humidity. They can be configured to the customer's requirements on the production line, but configuration and parameters can also be set by the user. The series has both analogue and serial outputs as well as several options: different cable lengths, power supply modules and serial interface modules as well as a local display.

-HMP231 for wall mounting
-HMP233 for installation directly in processes in tight spaces
-HMP234 for installation directly in processes & for measurement in pressures from vacuum to 10 MPa (100 bar)
-HMP235 for installation directly in processes & for measurement in temperatures from -40 to +180 ºC
-HMP238 for installations in pressurized pipelines to as high as 40 bar (4 MPa)
