Intrinsically Safe Humidity and Temperature Transmitter Series HMT370EX Series
For use up to zone 0 and 20
The intrinsically safe Vaisala 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, biogas production' paint booths and any other industry or process where intrinsically safe humidity or moisture in oil measurement is required.
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
- 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)
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.
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.

Vaisala INTERCAP® Humidity and Temperature Transmitter Series HMDW80 measure relative humidity and temperature in various building automation applications. Transmitters combine easy installation and reliable operation with a low requirement for maintenance.
The versatile Vaisala HMDW80 series includes transmitters for wall and duct mounting, IP65-classified transmitters for humid areas, and transmitters with a radiation shield for outdoor use. It also includes temperature-only transmitters and transmitters with an optional display.
Calculated humidity parameters –dew point temperature, wet bulb temperature, and enthalpy – are also available.
The current loop-powered, two-wire transmitter is called the Vaisala HMT120 and the three-wire transmitter - with voltage and serial line outputs as well as a relay - is called the Vaisala HMT130. The new transmitters utilize the fully interchangeable HMP110 probe.
The transmitters replace with enhanced features the currently very successful HMT100 transmitters. The HMT120 and HMT130 transmitters are especially designed for cleanroom continuous monitoring systems and are very easy to clean. The housing is also durable for continuous exposure of cleanroom cleaning agents and the interchangeable measurement probe is equipped with the latest humidity sensor technology, the HUMICAP180R.
The Vaisala HUMICAP® Digital Humidity Module HMM105 is an open frame module for integration into environmental chambers. The modules provide an I2C output
for relative humidity (RH) or dew point (Td). The module consists of a detachable probe assembly – a probe head with M10x1 threads and a flex cable – and the module circuit board. The probe assembly is 30 cm in length. The module incorporates the Vaisala HUMICAP® 180R sensor which ensures excellent measurement accuracy.
Humidity And Temperature Transmitters For High-Accuracy Measurements In HVAC Applications HMD110 HMW110 HMS110
Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMDW110 measure relative humidity and temperature in multiple HVAC applications. The series includes transmitters for duct mounting, IP65-classified wall transmitters, and outdoor transmitters with integrated radiation shields.
Vaisala HMDW110 series transmitters are equipped with trusted HUMICAP® 180R sensors. They are individually adjusted and delivered with a calibration certificate. The factory calibration is traceable to NIST. Transmitters can be field-calibrated using either an HM70 Hand-Held Humidity and Temperature Meter, or a PC connection.
The Vaisala 2000 recorder combines internal temperature and RH sensors with an optional external channel for either current or voltage inputs for recording parameters such as differential pressure, CO2, level, particles, or conductivity. The Vaisala 2000 recorder can include a Boolean channel for door switches or alarm contacts.
The Vaisala continuous monitoring system is ideal for both light and heavy industrial environments, as well as GxP-regulated applications, the system integrates a wide selection of data loggers, transmitters and Modbus devices to monitor several parameters: temperature, relative humidity, dew point temperature, CO2, differential pressure, door contacts, and more. The viewLinc software is backwards compatible and able to access data created with older versions of the software.
