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, biogas production' 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: ATEX IECEx This next-generation HMT370EX transmitter replaces the long-running HMT360 transmitter series. 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 Models for measuring moisture in oil and jet fuel: HMP378F - for moisture in oil HMP378H - for JET A-1 fuel The HMT370EX uses the superior Vaisala HUMICAP technology. Features Intrinsically safe (Exi) Interchangeable probes Detachable probe module Graphical LCD display and non-display model Vaisala HUMICAP® sensor Compatible with Vaisala Insight PC software Traceable calibration (certificate included) + Show more Key Benefits Intrinsically safe The entire HMT370EX transmitter can be installed directly in explosive areas. It can withstand continuous exposure to potentially explosive environments that contain flammable liquids, gases or dust. Operation in any of these environments requires no additional protective enclosures. Detachable probes Probes can be easily replaced and removed for calibration outside the hazardous area without removing the entire transmitter. Attaching new probes involves minimal reconfiguration, as up-to-date settings can be restored from the transmitter. Easy to configure Output configuration and measurement calibration and adjustment can be carried out directly on the optional local display interface. Alternatively, you can connect the transmitter to Vaisala Insight PC software and configure both the transmitter and the probe together or separately.
