Description

Please note that the HMT370EX has been released with IECEx, ATEX, FM, NEPSI, KC, and MET certificates for intrinsically safe compliance, but CSA approval is still pending.

The intrinsically safe HMT370EX is the ideal solution for use in hazardous areas up to zone 0 and 20. In addition to measuring relative humidity and temperature, the transmitter outputs also other humidity parameters: dew point temperature, wet-bulb temperature, absolute humidity, mixing ratio, water concentration, water mass fraction, water vapor pressure, and enthalpy. Special models for moisture in oil and jet fuel measurements are available.

Typical applications include fuel storage tanks, manufacturing of chemicals, pharmaceuticals and food, paint booths, and any other industry or process where intrinsically safe humidity or moisture in oil measurement is required. View the current certificates for the HMT370EX:
