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
