MJ159, MJ359, 212159 and 212359

Major Megger Insulation Testers

  • No scale multipliers
  • Multiple test voltages for spot and step voltage testing
  • Guard terminal to eliminate surface leakage current

The MJ459 and MJ159 replace the BM12 and MJ10, respectively.

Two models are available for general purpose testing which include a low-voltage model.

Both are portable, self-contained instruments designed to give rapid and accurate measurements.The models feature an analog display having four selectable test voltages of 100, 250, 500 and 1000 V dc, measuring insulation resistance up to 2000 MΩ and an ohm range to 5000 ohms.
