Product DescriptionHMM100 Humidity Module for Environmental Chambers Features/Benefits · Full temperature compensation over the operating temperature range of -70C ... +180C · High temperature tolerance, also suitable for heatsterilization · Excellent measurement accuracy with Vaisala HUMICAP® 180R sensor · Durable · Easy field calibration by trimmers · Maintenance-free · Easy to install · Applications: test chambers, incubators The HMM100 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). Two probes are available, one made of plastics, the other of stainless steel. Several cable lengths up to 3 meters are available. Both the probes have the Vaisala HUMICAP® 180R sensor which ensures excellent measurement accuracy. Robust and Reliable The HMM100 probe works in freezing conditions (-70 °C) and also in temperatures up to +180 °C. The 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. Maintenance-free Compared to psychrometers, the HMM100 is practically maintenance free. 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.
