  • Accuracy better than 2C dewpoint equivalent
  • Issued with a Certificate of Calibration traceable to International Humidity Standards
  • On board pressure dewpoint calculator, including data for Natural Gas
  • AutoCal calibration adjustment to maintain accuracy between laboratory calibrations
  • Units selectable for C dp, F dp, ppm(v), ppm(wt), gm/m or lb/MMSCF
  • Molecular mass pre-loaded for ppm(wt) in common gases, can be entered for other gases
  • Two fully programmable alarms with relays and annunciator LEDs
  • Current output linear for selected units
  • RS485 port for digital output of measured value
  • Large, easy to read, 5-digit LED display
  • Front panel IP54
