The Dwyer RP2 Wireless Thermo-Hygrometer Probe measures relative humidity, temperature, dew point, and wet bulb temperatures when combined with the Model UHH Universal Handheld. In order to protect the sensor in higher air flow ducts, each probe comes with a membrane filter. Factory calibrated replacement humidity sensors can plug directly into the probe without requiring additional calibration.

Wireless probes can take measurements up to 50 feet away from the UHH. A bicolor LED flashes on the handle of the probe to indicate communication status with the handheld. The battery is rechargeable via the mini-USB connector on the bottom of the probe.
