Insulation Testers

SANWA insulation testers check insulation resistance at selectable test voltages, from analog single-range models to a 5000 V digital tester reading up to 1 TΩ. The digital models add live-circuit detection and auto discharge. Bhumika is SANWA’s authorized Canadian distributor and provides quotes for Canada.

What should I consider before buying?

Match the test voltage to the job: HG561H covers 15–500 V, MG500 125–500 V, MG1000 250–1000 V, MG102 six ranges from 50–1000 V and MG5000 250–5000 V. MG5000 adds DAR and PI and reads up to 1 TΩ. MG1000 and MG500 are IP54 with a 30 V live-circuit inhibit; MG102 and MG5000 list CAT IV ratings. The five analog models (PDM1529S, PDM5219S, DM1009S, DM509S, PDM509S) differ by test voltage and scale.

What do buyers usually ask?

Which insulation tester goes to the highest voltage?

MG5000 provides DC 250 / 500 / 1000 / 2500 / 5000 V test voltages and insulation resistance up to 1 TΩ, with DAR and PI functions.

Do these testers detect a live circuit?

The digital models MG102, MG5000, HG561H, MG1000 and MG500 list automatic live-circuit detection that prevents the insulation test on a live circuit. MG1000 and MG500 trigger at 30 V AC/DC or more.

What separates the analog models?

PDM1529S has 250/500/1000 V ranges to 2000 MΩ and PDM5219S has 125/250/500 V ranges to 100 MΩ. DM1009S, DM509S and PDM509S are single-range: 1000 V/2000 MΩ, 500 V/1000 MΩ and 500 V/100 MΩ.
