The HC2-S(3)-HEATED is suitable for use wherever high humidity with the possibility of condensation is present. Equipped with an automatic sensor heater, the probe is activated cyclically and prevents condensation on the sensor.
Rotronic HC2-S3 Heated
Description
Equipped with an automatic sensor heater, the probe is activated cyclically and prevents condensation on the sensor.
Application
The HC2-S(3)-HEATED is suitable for use wherever high humidity with the possibility of condensation is present. Typically, when condensation occurs long dry out periods are required or false readings are measured. This is often the case in environmental chambers, food manufacturing, tunnels/caves and many other applications.
Features
- Measures relative humidity, temperature and dew point
- Outstanding accuracy and repeatability
- Automatic heating function
- Eliminates of condensation
- SMD Thermo sensor element
