Patented Impeller and Sensor Technology
Features a large, impeller mounted on a sapphire jewel bearing, which means it starts rotating with the slightest puff of air, and this unique impeller is user-replaceable, too, which means it can easily be replaced if it is damaged or worn.
If your application demands regular calibration, simply pop in a new impeller and the instrument is restored to like-new factory calibration standards.
The humidity sensor can be recalibrated in the field using the optional Relative Humidity Calibration Kit.
