Flagship Humidity and Temperature Transmitter HMT330 Series
Vaisala HMT330 series are easy-to-use transmitters for demanding industrial and air conditioning applications. The transmitters measure relative humidity and temperature and from these calculate dew point and wet bulb temperature, mixing ratio and absolute humidity. They can be configured to the customer's requirements on the production line, but configuration and parameters can also be set by the user. The series has both analogue and serial outputs as well as several options: different cable lengths, power supply modules and serial interface modules as well as a local display.

Vaisala HUMICAP® Humidity and Temperature Probe HMP8 is designed for pressurized applications in compressed air systems, refrigerant dryers, and other pressurized industrial applications where easy insertion and removal of the probe and adjustable installation depth into the pipeline are needed. The HMP8 is part of the Indigo product family and compatible with Indigo500 and Indigo200 series transmitters and free Insight PC Software.
Humidity and Temperature Probe HMP3
for general purpose humidity and temperature applications with exchangeable sensor
Vaisala HUMICAP® Humidity and Temperature Probe HMP3 is a general-purpose probe designed for processes with moderate humidity and temperature levels. The probe structure allows the sensor to be replaced in the field without tools, making it suitable for applications such as industrial HVAC systems, paint booths, cleanrooms, environmental chambers, and applications where periodic recalibration is not sufficient for maintenance.
HMP3 is part of the Indigo family and is compatible with Indigo500 and Indigo200 series transmitters. It can be used with Vaisala Insight PC software for data visualization, easy probe configuration, and field calibration.
Vaisala's HMT360 humidity and temperature transmitter is designed for use in potentially explosive atmospheres. The electronics are designed so that the transmitter is intrinsically safe. The whole transmitter can be installed directly into an explosive area, even into areas classified as having a constant risk of explosion (Zone 0). HMT360 fulfils all requirements of current standards. The microprocessor-based HMT360 is easy to install, maintain and calibrate due to its modular structure. The interchangeable probes are easy to remove and enable on-site calibration. They make the HMT360 series versatile and ensure its suitability for almost any application.
Also suitable for measuring water activity of Jet Fuel
The Vaisala HMT140 wireless data logger is designed for humidity, temperature and analog signal monitoring in warehouses, freezer and cryogenic farms, laboratories, blood banks and many other life science applications.
The Vaisala HMT140 incorporates Vaisala HUMICAP® technology to measure relative humidity and temperature accurately and reliably. The Vaisala HUMICAP sensor is resistant to dust and most chemicals. Alternatively, the Vaisala HMT140 can connect to Resistance Temperature Detectors (RTDs), Voltage, Current and Contact sensors, making the Vaisala HMT140 the most versatile Vaisala data logger for life science applications.
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.
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
Humidity and Temperature Probe HMP1
for wall mounting
Vaisala HUMICAP® Humidity and Temperature Probe HMP1 is designed for measuring ambient measurement in indoor spaces. HMP1 can be directly connected to Indigo200 series transmitters to form a single wall-mounted unit. Its probe head and body are integrated to a single unit and it uses the miniature 5 mm (0.2 in) diameter HUMICAP® sensor and head for great stability and fast response time.
HMP1 is part of the Indigo product family and compatible with Indigo200 and Indigo500 Series Transmitters. HMP1 can also be used with the Vaisala Insight PC Software for data visualization, easy probe configuration and self-calibration.
The new Vaisala HM70 portable humidity meter provides fast and convenient spot-checks of relative humidity and temperature. Apart from that, it can be also used to calibrate other Vaisala humidity instruments such as HMT330, HMT120, HMT130, HMW90, HMD90, HMW110, HMD110
All Dickson chart recorders feature a large 8″ or 6" chart and user-selectable recording timeframes (1-day, 1-week, 1-month) and ranges.
The Vaisala HM40 is a compact, robust and affordable hand-held meter for various portable measurement applications. It is an ideal spot-checking tool that is easy to use and provides reliable measurement. The HM40 hand-held utilizes the interchangeable HMP110 probe that was launched earlier this year and is equipped with the latest humidity sensor technology, the HUMICAP® 180R.
