Vaisala HMT360 Intrinsically Safe RH&T transmitter models…

  • Vaisala HMT361 wall mount RH&T transmitter
  • Vaisala HMT363 for duct mounting and tight spaces
  • Vaisala HMT364 for high pressures up to 100 bar (and vacuum) conditions
  • Vaisala HMT365 for high temperatures up to 180°C
  • Vaisala HMT367 for high humidity and meteorological applications
  • Vaisala HMT368 for pressurized pipelines up to 40 bar, with optional ball valve mount

 

The interchangeable probes enable fast and easy removal or re-installation when required. Calibration, for example, is easy to perform due to the modular structure. All calibration coefficients are included in the probe unit itself, which means that probes can be switched between transmitter bodies without losing the accuracy.  Fluidic are set-up to offer UKAS traceable RH&T calibration in our Glasgow office.  Please contact 0141 641 5920 for information.

 

Specific features of the Vaisala HMT360 Series of RH&T transmitters include…

  • Interchangable probes
  • Calibration certificate as standard on every model
