技术说明
For this version of the HMP45C Temperature and RH Probe, the cable has a military style connector instead of pigtails. The connector attaches to the RAWS-F Fire Weather Quick Deployment Station. The HMP45C-QD 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.
