Advanced Humidity Module HMM170

  • for environmental chambers including vacuum and high pressure chamber

Vaisala Humidity and Temperature Module HMM170 is a robust open frame transmitter for integration into environmental chambers that need accurate and reliable measurement even in demanding conditions including vacuum or high pressure.

The module is built to last for years and it is easy to integrate into the chamber and the circuit board. Both digital and three configurable analog output channels are available, ensuring compatibility for most chamber types. In addition to relative humidity and temperature, dew point and other calculated parameters are available.

The HMM170 provides a digital RS-485/Modbus RTU output and three freely configurable analog output channels. The module provides relative humidity, temperature, dew point, and other calculated parameters.

Designed for harsh environments

HMM170 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 technology

The 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 Installation

HMM170 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.
