LogR Corrosion Monitor

LogR Corrosion Rate Monitor

The ProMinent® Log/ R is a single channel corrosion rate monitor using Linear Polarization Resistance (LPR) to measure the corrosion rate of metals. Weight loss coupon results can take weeks or months. With the Log/R, a reading is taken every 2.5 minutes giving accurate corrosion rates instantly. Select from carbon steel, copper or admiralty sensors.

Package Includes

  • Monitor, sensor, 24VDC/120VAC power supply
  • Universal power adapter
  • 3/4" sentry "T" fitting
  • Backplate mounting hardware
  • USB flash drive with startup and O&M manuals
Choose one of the following packages:
  • Carbon Steel sensor package (P/N 7760788)
  • Copper sensor package (P/N 7760789)
  • Admiralty sensor package (P/N 7760790)

Features & Benefits

  • No lengthy corrosion coupon delays - instant measurement
  • Corrosion rate updates every 2.5 minutes
  • Data logs every 5 minutes
  • Stores up to one year of log data
  • Pre-configured for your metallurgy
