The RH40 series relative humidity sensors from Environdata Australia feature a field interchangeable tip that doesn’t need field re-calibration. They use semiconductors and a thin film polymer that changes di-electric constant with atmospheric relative humidity.
The technology employed results in a linear output change as a function of relative humidity. It should be noted that electronic relative humidity sensors are not recommended for accurate measurements above 95% relative humidity or for polluted environments.
The RH40 series relative humidity sensors are protected from insects and the like by filters.
Features of RH40 series humidity sensors:
- Inter-changeable tip
- Reliable humidity measurements
- Linear output frequency
- Robust construction
