Vaisala HMM100 Humidity Module is designed to be integrated into environmental chambers. It offers a single analog output channel for either relative humidity (RH) or dew point (Td). Two types of probes are available: stainless steel or plastic. The plastic probe comes in two sizes, standard and extended (400 mm long), with various cable lengths available up to 3 meters. Both probes use the HUMICAP 180R sensor, ensuring accurate measurements.

Benefits

  • Excellent measurement accuracy
  • Low-maintenance
  • Easy to install
  • Durable

Robust & Reliable

Vaisala HMM100 probe works in freezing conditions (-70 °C (-94 °F) and also in temperatures up to +180 °C (+356 °F). HMM100 is easy to install and the probe can be freely placed in a test chamber as the speed of airflow does not affect the measurement.

Low Maintenance

Compared to psychrometers, Vaisala HMM100 requires very little maintenance. There is no wick that needs changing and there is no need for a water tank or water pump. Thus, environmental stress screening can be done reliably.

Accessories

The accessories available are a component board mounting bracket with a lid, probe clamp, USB cable for service use, a module housing, and a probe mounting flange.
