Every InstantMPY analyzer measures corrosion using linear polarization resistance, the same proven way used in oil and gas pipelines for decades and recognized by ASTM International for online corrosion monitoring. Choose the model that fits how you want to work. No maintenance, no calibration: replacement electrode tips cost about $30 a year, and the useful instrument life is 10 years.

XM2020 Corrosion Monitoring System

$4,995 plus probe

For in-system use. Everything the CM2012 measures, plus a SCADA link so your corrosion rate lives on the same screens as the rest of your plant data.

  • SCADA integration via 4-20 mA HART output
  • 3 electrode LPR probe
  • LCD display on the unit
  • Rated Type 4x / IP66, operating range -40 C to +70 C (-40 F to 158 F)
