Description

The THP-W Temperature Humidity Probe is a self‐contained unit with a solid-state temperature/humidity sensor giving a linearized output of 10mV per °C and 10mV per %RH respectively. The unit operates from 5‐12 volts DC. Connection is via a standard circular stainless steel DIN connector. The mating connector with 8 ft. (2.4 m) cable is supplied. The probe operates within ± 0.4°C over a –40 to 120°C temperature range. The humidity output is accurate to ± 3% (typical) between 20 to 80%RH and ± 4% between 10 to 90%RH. The probe housing is made of rugged anodized aluminum with a plastic end cap. The sensor is housed under a water-resistant membrane. When used with the Monarch Instrument DataChart™ DC1250 Paperless Recorder, no additional power is required as power is provided directly from the rear terminals of the recorder.
