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.
The probe can be freely placed in a test chamber as the speed of airflow does not affect the measurement.
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.
