SF6 Moisture Measuring Device
With Built-In Recovery

Download Data Sheet Here

The 3-038R-R303 Multifunction Analyzer is the latest addition to the 3-038 series devices. The new model includes a color touch screen and an integrated recovery system allowing zero-emissions testing. The test gas is captured and pumped back into the switchgear through the onboard storage vessel and compressor. Like our previous multifunction analyzers, this device is able to test SF6 purity (vol. %), moisture content, and byproducts (SO2). The user can select pass/fail values for the gas being tested, as well as, the units of measure (details in key features) and save up to 100 test results and names (dates and time are stored automatically). The exterior consists of a rugged and weatherproof case, complete with locking hasps, roller wheels, and telescoping handle.

Key features:

  • 5.7”color touch panel
  • Indication of SF6 concentration in volume percent
  • Indication of moisture concentration in dew point °C or °F, referred to atmospheric or input pressure, reversible to indication in PPMv or PPMm
  • Indication of SO2 concentration in PPMv
  • Input pressure indication in bar pa, pe, psi, kPa, or mPa
  • Transfer of measured data to USB thumb drive or USB cable to PC
  • Very easy handling by exchange of the modules for calibration
  • Automatic identification of the residual lifetime of the sensors
  • Setting of limit values for volume percentage, dew point temperature, and SO2
  • Menu item in German, English, French, Spanish and Italian
