0- 1200 ohm 3 Point Ground / Earth Resistance Tester
 
Associated Research 251 Features
  • Self-contained synchronous vibrator, battery powered unit
  • Capable of measuring earth resistivity or the true resistance to earth of man-made grounds
  • Not affected by the resistance of the leads ( terminals 1 & 2 only)
  • Stray AC or DC currents in the earth do not detract from its accuracy
  • Three resistance ranges: 0 to 12 ohms, 0 to 120 ohms, 0 to 1200 ohms
Associated Research 251 Applications
  • Three Electrode Method, for determination of average earth resistivity.
  • Three Electrode Method, for the measurement of resistance to earth of man-made grounds, anode resistance, polarization effects
  • Two Electrode Method, for the measurement of circuit resistance
  • Available with ground rods & cable set
