Model IA Analog Electronic Potential Meter

Description

Model IA Analog Electronic Potential Meter (Cat. #4107)

The Model IA Analog meter is designed for use by non-technical personnel including crews, servicemen, meter readers, etc., but it is also suitable for the most experienced engineers and technicians.

The 10 megohm 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
  • 0 – 2 volts or go-no-go
  • Includes electrode and two leads
  • Optional electrode extension
