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.
The HMT370EX offers several probe options for different applications:
• HMP371 – for wall mounting
• HMP373 – for confined spaces
• HMP374 – for pressurized spaces
• HMP375 – for high temperature
• HMP377 – for high humidity
• HMP378 – for pressurized pipelines
