Volt/Multi Meters

Model DPM Digital Electronic Potential Meter

Cat. #4110
Price $420.00
For Electrolysis, Corrosion and Cathodic Protection Testing

Designed for use by non-technical personnel including crews, servicemen, meter readers, etc., but also suitable for the most experienced engineers and technicians.

20MΩ input resistance practically eliminates low potential readings caused by resistance in the external circuit due to contact resistance of the reference electrode. This condition is frequently encountered in city work and in frozen ground.

  • Low cost
  • Rugged
  • Easy-to-use
  • Structure to earth potentials
  • Auto-polarity + 2V and +20V ranges
  • Low-battery display
  • Optional electrode extension
