The HMP45C is a rugged, accurate temperature and relative humidity probe. It measures relative humidity over the range of 0 to 100% RH and temperature over the range of -40° to +60°C. This probe is suitable for long-term, unattended monitoring, and is compatible with all Campbell Scientific data loggers. The "-L" on a product model (HMP45C-L) indicates that the cable length is specified at the time of order.
