HMP50-ET Vaisala Temperature/RH Probe for ET Station, 54 inch cable


For this version of the HMP50 Temperature/RH probe, the cable terminates in a connector and is the ideal length for attachment to the ET107 or  ET106 ETo Weather Station. The HMP50-ET measures temperature with a 1000 Ohm platinum resistance thermometer (PRT) and relative humidity (RH) with a 50Y Intercap humidity sensor. The chip can be replaced in the field by the user, thereby eliminating the downtime typically required for the recalibration process. In the image, there is an HMP50-ET housed in a radiation attached to the ET107's crossarm.
