Key Features digital insulation tester Bangladesh

1. Five DC test voltages (50V, 125V, 250V, 500V, 1000V), so technicians can match the output to the equipment under test
2. Insulation resistance measurement up to 4000 MOhm, which covers demanding industrial and building applications
3. Built-in 200 mA continuity check with 0.01 Ohm resolution, therefore enabling grounding line verification without a separate meter
4. CAT III 600V safety rating, which qualifies the tester for use on distribution panels and low-voltage installations
5. Comparator PASS/FAIL function with beep and LCD color change, so results reach the technician even without watching the screen
6. Built-in AC/DC voltage meter up to 600V, useful for checking solar arrays and EV systems before insulation testing
7. Drop-proof housing that withstands a 1-meter fall onto concrete, delivering reliable performance in rough field conditions
8. White LED backlight and FSTN LCD, allowing accurate readings even in dim electrical rooms or basements
