Designed for harsh environmentsHMM170 probe covers the full temperature range -70 … +180 °C (-94 … +356 °F) used in climate chambers and the whole humidity range up to condensation. The small probe and compact component board offer easy and flexible installation. The probe cable options (2, 5, or 10 m (6.5, 16.4, or 32.8 ft)) offer excellent cost optimization and flexibility to any OEM application. By ordering HMM170 with the appropriate sensor, you can use the module in environments that are frequently sterilized with vaporized hydrogen peroxide (H2O2) or to measure humidity in oil medium, for example, for transformer and engine monitoring applications. Robust sensor technologyThe latest general purpose HUMICAP R2 sensor has improved corrosion resistance. The sensor can tolerate typical chemicals, such as cleaning agents used in climate chambers. The automatic sensor chemical purge function keeps the sensor clean from typical chemical fumes and the additional probe warming function prevents condensation. In case HMM170 gets in contact with water, the automatic heating rapidly dries the sensor to enable fast and accurate humidity measurement. Easy InstallationHMM170 is easy to install and convenient to use. It provides both digital and analog outputs for multiple needs. An integrated service port enables a quick and simple way to configure, check, and calibrate the module with the help of a USB cable and Vaisala Insight PC software. In addition, the footprint of the HMM170 component board enables easy update for Vaisala HMM100 users. |

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.
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.
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:
Models for measuring moisture in oil and jet fuel:
