Figure 17 QMH102 Temperature and Relative Humidity
Sensor
The QMH102 probe is designed for the measurement of relative
humidity and temperature. Humidity measurement is based on the
capacitive thin film polymer sensor HUMICAP
180. Temperature
measurement is based on resistive platinum sensors (Pt 100 and Pt
1000). Both the humidity and temperature sensors are located at the
tip of the probe and in the standard version is protected by a
membrane filter. The QMH102 temperature output is passive
(resistive output Pt 100).
