Overview
The HMP45C-LQ is a rugged, accurate temperature and relative humidity probe. The sensor measures relative humidity over the 0 to 100% RH range and temperature over the -40° to +60°C range.
Key Advantages
Cabled for use with RAWS stations
Technical Description
For this version of the HMP45C, the cable terminates in a military style connector and has a user-specified lead length. The connector attaches to the RAWS-P enclosure, which mounts to a CM6/CM10 tripod, CM110-series tripod, or UT-series tower. The probe uses a HUMICAP capacitive polymer H chip to measure relative humidity over the 0 to 100% RH range. A PRT measures temperature over the -40° to +60°C range.
Benefits
- Well-suited for long-term, unattended applications
- Accurate and rugged
