The 41382 probe combines a high accuracy, capacitance-type humidity sensor and precision platinum RTD temperature sensor in one probe. The sensor is mounted in a weatherproof junction box for convenient wiring. Output options are available for 0-1 VDC, and 4-20mA. For accurate measurements, the relative humidity and temperature probe should be installed in a protective radiation shield. Use of the probe without a radiation shield may result in large errors due to solar heating. The probe installs easily in the Model 41003P naturally ventilated or Model 43502 aspirated shield. The relative humidity and temperature probe is designed to offer years of service with minimal maintenance. As with most humidity sensors, humidity calibration may drift slightly with time. Recalibration will restore the probe to acceptable limits. | ![]() | |
