    Moisture Analyzer. The 3-037-R002 moisture measuring device was designed from the ground up, to be used on arced SF6. Unlike conventional multi-gas hygrometers, the 3-037 is specifically calibrated for the unique characteristics (i.e. densities, molecular weights, and acidity) of faulted SF6. 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.
