The sensor's sealed, corrosion-resistant and nonconductive housing resists condensation and contaminants, to make data collection hassle free. Now, with long term calibration-free operation, the WaterLOG® Relative Humidity / Temperature Probe (H-380) features outputs and simple field maintanance options to fit your application.
The Relative Humidity / Temperature Probe (H-380) combines a capacitance type humidity sensor and temperature sensor to deliver accurate measurements from one compact, durable probe.
- Temperature measurement with precision RTD probe provides fast response and high accuracy
- Linear voltage or current output signals for transmission over long distance
- Operating temperature range of -40° to 60° C
- Fully interchangeable HygroClip module is quicky replaced in the field with no loss of accuracy and no calibration
- Digital and analog outputs
- Low heat absorption color
