Measuring in High Humidity & Condensing Environments - Warmed Probe Technology

From Vaisala
 

 

Reliable, stable, and accurate humidity measurement in high relative humidity (>85%) and condensing environments has always been next to impossible without specialized technology. High RH and resulting water on the humidity sensor usually causes problems such as higher uncertainty, higher drift, no reading while water is on the sensor, causes extra calibration service. Warmed probe technology resolves these issues and provides a reliable, repeatable and accurate measurement in high RH conditions.
