HIOKI IR4057-20 5 Range Digital Insulation Resistance Tester Megohmmeters 50 to 1000V Periodic Inspection
Product Description:
- Hioki insulation resistance testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The IR4057-20 is a 5-range, 50V to 1000V digital insulation resistance tester with bargraph, and delivers efficient functions and features to help shorten work time associated with field insulation testing.
- 5-range testing voltage of 50 V/100 MΩ to 1000 V/4000 MΩ
- Stable & high-speed digital readings, 0.3 second response time for PASS/ FAIL decisions
- Drop proof onto concrete from 1m (3.28 feet)
- Bright LED, luminous LCD, test lead with bright LED lamp to illuminate near hand (Option L9788-11 or L9788-10)
- Continuity check via 200 mA testing
- Built in AC/DC voltage meter, useful for testing solar power generation systems and electric vehicles
