OVERVIEW:

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

FEATURES:

• 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


• LPR technology


• CE Approved


• Alarm Relay
