MG500

IP54 digital tester, 125/250/500 V to 4000 MΩ, live-line alarm.

  • 125–500 V
  • 4000 MΩ
  • IP54

The SANWA MG500 is the lower-voltage sibling of the MG1000, with 125, 250 and 500 V test voltages to 4000 MΩ in the same IP54 body. It shares the live-circuit inhibit at 30 V, bar graph, data hold and 200 mA continuity test, and adds a 400 kΩ range. Bhumika quotes this model for Canada.
