The 3-037-R002 moisture measuring device was designed from the ground up, to be used on arced Sulfr hexafluoride. Unlike conventional multi-gas hygrometers, the 3-037 is specifically calibrated for the unique characteristics (i.e. densities, molecular weights, and acidity) of faulted Sulfr hexafluoride. Not only is the device consistently more accurate and reliable, the typical long-term drift (and subsequent need for factory recalibration) associated with non gas-specific devices is all but eliminated.
