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, but the typical long-term drift (and subsequent need for factory recalibration) associated with non gas-specific devices is all but eliminated.
The exclusive DILO sensor measures SF6 at atmospheric pressure which removes pressure and temperature variables from moisture readings. Additionally, the electronic flow meter not only reduces the sample to a trickle, but the orientation of the device is no longer relevant – making the 3-037 far more suitable for on-site testing. All readings are displayed in parts per million by volume (PPMv).
