AEMC 1210N 1326.01 500V Hand-Cranked Megohmmeter Insulation Resistance Tester

The AEMC 1210N 500V Hand-Cranked Megohmmeter is a compact and self contained True Megohmmeter that is practical and dependable.


The 1210N is engineered for a wide range of field and plant service applications. The effortless hand cranked operation provides a steady, rectified DC voltage output along the entire range for consistently reliable readings. The 1210N also permits resistance testing to 500 kOhms and continuity testing to 100 Ohms. The 600 Volt test voltage range is used to perform safety checks to confirm that the sample is fully discharged and not connected to an energized circuit.


1210N Features

  • True Megohmmeter
  • Test voltages to 500 Volts
  • Insulation measurements to 200 Mega Ohms
  • LED indicates proper cranked speed and constant voltage output
  • Automatic discharge when measurement is done
  • Auto Ranging - dual scale operation for increased sensitivity and easier reading
  • Designed for harsh environments of mining, marine, heavy duty field, military, and industrial use
  • Extra heavy duty cast aluminum case, O ring sealed to protect from rain, water and dust
  • Aluminum lid
  • Compact self contained package with folding crank
  • Large direct reading scale
  • CE Mark


  • Acceptance testing
  • Preventive maintenance
  • Test motors, electrical wiring installations, switchgears, and cables
  • Continuity checks
  • Check industrial and domestic contracting
