Sling Psychrometer in a rugged, self-contained, protective carrying case. Standardizing dynamometer horsepower readings requires accurate relative-humidity and temperature data. The most precise way to capture this vital test information is by using a sling psychrometer. It is a must for manual humidity information entry and also a great way to verify (or reset) your automatic weather station’s calibration. Simple to use, it takes less than a minute to get a precise relative-humidity reading – works at the racetrack, too.
