HMP50 Temperature and Relative Humidity Probe

The HMP50, manufactured by Vaisala, measures air temperature with a 1000 ohm platinum resistance thermometer (PRT), and RH with the INTERCAP® capacitive chip. The chip is field replaceable, as needed, and eliminates the downtime typically required for the recalibration process.

Features

PRT used for temperature measurement
Capacitive RH chip used for RH measurement
41303-5A radiation shield recommended when exposed
to sunlight
A HMP50 housed in a 41303-5A can be mounted to a mast
or crossarm
