MJ15_Model

MJ15 and BM15 5KV Insulation Resistance Testers - Megger

 (2)

The BM15 and MJ15 are compact 5-kV insulation testers that are simple to use and provide a quick, accurate reading of insulation resistance. Both instruments offer four test voltages (500 V, 1 kV, 2.5 kV, 5 kV), analog scales, and measurement sensitivity to 20 Gohm.

Both units include “pass/fail” display overlays for a rapid “go/no go” testing and trend analysis.

The BM15 is powered by 8 “AA” or rechargeable alkaline batteries while the MJ15 includes a hand-crank generator in addition to battery power.


MJ159_Model

MJ Series 1KV Insulation Resistance Testers - Megger

 (2)

MJ Series The MJ159 is the recognized industry standard, upgraded with modern circuitry. This analog Meter allows the trained operator to determine much more from the needle movement than just a Mohm reading. Available in line, battery or hand cranked models.

Other features include:
  • IR measurements to 2000Mohm
  • Four test voltages to 1kV
  • Guard terminal
  • Continuity and kohm functions for troubleshooting
