Vaisala Thin Humidity & Temperature Probe HMP42 (14209) Check Availability

The HMP42 is a temperature and humidity probe used with the Vaisala Humidity & Temperature Indicator HMI41. The temperature measurement range for continuous measurement is -40 to 100 °C ( -40 to 212 °F) and for short term temperature measurements, the range is -40 to 180 °C (-40 to 356 °F). It has a temperature accuracy of ±0.2 °C (±0.36 °F) at 20 °C (68 °F). The relative humidity measurement range is 0 to 100% RH. The relative humidity accuracy is ± 2% at 0 to 90% RH and ± 3% at 90 to 100% RH. The probe is 9.25” long. With a diameter of 0.16”, this probe is thinner than other probes compatible with the HMI41 which is useful for making measurements in tight spaces and in ductwork.
