Megger MIT481 Insulation & Continuity Tester, 50V Min, 1000V Max, 200GΩ Max, CAT IV 600 V

Telecommunication insulation and continuity testers developed to meet the special requirements of telephone line testing, as well as the requirements of electrical contractors and industrial testing to CATIV 600V. All instruments meet TNV3 as well as IEC1010, HD384 and BSEN61557. The insulation test inhibit voltage has been raised to 75V to overcome interference between cables experienced at lower voltages, compared to 50V for standard cable testing.

All models:
Complies with EN 61010-1 CATIV 600V safety rating
200mA & 20mA Continuity testing
Insulation test voltage display
75V test inhibit
TRMS and DC Voltage measurement
Dual Digital Display and Analogue bar-graph
