Model HMP45C Temperature and Relative Humidity Probe

The HMP34C Temperature and Relative Humidity probe contains a Platinum Resistance Temperature detector (PRT) and a Vaisala HUMICAP 180 capacitive relative humidity sensor. Its accuracy is 2% over 10-90% RH; 3% over 90-100% RH. It is ideal for long-term, unattended application. Power is only supplied to the HMP45C during measurement, which reduces the current drain.
