The HMP45C-LC 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.Read More
The "-LC" version of this product terminates in a connector (instead of pigtails) for use with a CS110 Electric Field Meter or MetData1 Weather Station. The length of the cable is specified at the time of order.
This version of the HMP45C has a connector instead of pigtails for connecting the sensor to a MetData1 Weather Station or CS110 Electric Field Meter. The probe uses a HUMICAP capacitive polymer H chip to measure relative humidity, and a PRT to measure temperature. Relative humidity range is 0 to 100% RH, and temperature range is -40° to +60°C. A solar radiation shield is required if the probe will be exposed to sunlight.

The connector can be attached to the CS110 Electric Field Meter or MetData1 Weather Station. The CS110 has a CR1000 and the MetData1 has an on-board CR10X.
The HMP45C-LC should be housed in a 41003-5 10-plate naturally-aspirated solar radiation shield. This radiation shield mounts to a tripod or tower mast, crossarm, or user-supplied pole.
