Digital humidity & temperature sensor with protective housing
Long-term stable, can be used in extreme temperatures (– 40 °C to +80 °C)
Very low power consumption
Easy connection to SDI-12 data logger, e.g. OTT netDL via digital interface SDI-12 (protocol V1.3)
Naturally-vented protective housing fitted with 7 lamellae
White outside coating and black inside coating for optimum protection against radiant heat
- Sensor is easily installed – simply insert it and tighten screw
Versatile
The OTT TRH unit reliably measures the relative humidity and temperature in a large variety of applications. It is used e.g. in automatic weather stations, often together with the OTT Pluvio series precipitation gauges. Other applications include environmental monitoring, hydro-meteorological applications, agricultural weather stations, and many more.
SDI-12 interface
The compact, long-term stability sensor has an SDI-12 digital interface through which the unit may output up to five values. In addition to the measured values for relative humidity and temperature, the sensor provides the calculated values for absolute humidity, dew point, and mixing ratio.
Well-protected
A protective cap prevents dirt, dust, and insects from entering the sensor system, avoiding inaccurate results. The weather and radiation protection included is UV and weather resistant and may easily be installed to vertical poles or horizontal pipes. It protects the sensor from solar radiation, precipitation, and wind thus ensuring precise measuring results.
