General Description
The HMP45C is a rugged, accurate temperature/RH probe manufactured by Vaisala Inc., that is ideal for long-term, unattended applications. The probe uses a capacitive polymer H chip to measure RH and a PRT to measure temperature. Power is only supplied to the HMP45C during measurement, which reduces the current drain. The probe connects directly to Campbell Scientific dataloggers that have a switched 12 V terminal such as the CR10X, CR23X, or CR5000. Dataloggers that do not have a switched 12 V terminal such as the CR510, CR10, or CR7 require an SW12V Switched 12 V device.For optimum results, the HMP45C should be recalibrated annually. An optional removable sensor head, model HMP41, can replace the HMP45C's sensing element while the sensing element is getting recalibrated. The HMP41 is compatible with any HMP45C. A radiation shield (Model 41003-X and R41046DS-24A Adaptor Plug, or UT12VA) should be used when the HMP45C is exposed to sunlight.
