Thermo-Hygrometer
A thermo-hygrometer is a combined humidity and temperature probe designed for meteorological and general outdoor applications. Operation from DC voltage and low power consumption makes it suitable for operation at remote locations. The linear output signals are consistent with the requirements of most data acquisition systems. For outdoor application it should be coupled with a radiation shield.
Features
- Temperature Sensor PT100 RTD and Capacitive Humidity Sensor
- High long-term stability
- Analogue and Digital outputs for humidity and temperature depending upon the models
- Early return after saturation
- Highly efficient radiation shield
- High protection from salty and polluted air
- Design and performances addressed to meteorological applications
