Overview

The SEN-R PRO HMP45A is Vaisala's top of the line relative humidity sensor. It conforms to the strictest meteorological requirements, in particular with respect to measuring relative humidity. Calibrated against factory references it can achieve accuracies of +2%rH in the critical range between 90% rH and 100% rH.

The Humicap® 180 sensing element is protected by a plastic cap and can easily be replaced. Maintenance is straightforward, and should field calibration be required the instrument can simply be taken apart and checked by means of Vaisala's Humicap® HMI41 Humidity Indicator.
