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 Module HMM100
- for environmental chambers
The Vaisala HUMICAP® Humidity Module HMM100 is an open frame module for integration into environmental chambers. The modules provide a single analog output channel for relative humidity (RH) or dew point (Td).
Practically maintenance-free HMM100 is an open frame module for integration into environmental chambers. Excellent measurement accuracy with Vaisala HUMICAP® 180R sensor.
- Full temperature compensation over the operating temperature range of -70˚C ... +180˚C
- High temperature tolerance, also suitable for heat sterilization
- Excellent measurement accuracy with Vaisala HUMICAP® 180R sensor
- Durable Easy field calibration by trimmers
Easy to install
The probe can be freely placed in a test chamber as the speed of airflow does not affect the measurement.
Easy field calibration by trimmers
HMM100 series modules have two trimmers mounted on the component board. These trimmers allow for easy adjustment of the offset and gain of the humidity measurement.
Compared to psychrometers, HMM100 requires very little maintenance. There is no wick that needs changing and there is no need for a water tank or water pump, which makes environmental stress screening reliable.
