Description
The digital insulation tester offers reliable measurement of resistance, AC voltage, and insulation resistance in a compact, battery-powered unit. The 0.65” LCD display provides clear readings up to 1999, with automatic zero adjustment for accurate measurements. Its rotary switch allows fast selection of ranges, while the continuity beeper confirms low-resistance paths quickly.
Designed for durability and safety, the tester includes overload protection, safety test leads, and a power-lock switch to maintain continuous measurement for up to 3 minutes. The device can measure OHMS (0–200 Ω), AC voltage (up to 600V), and Megohms (up to 2000 MΩ) with high accuracy. Its lightweight design (500g) and included accessories such as batteries, carrying case, and test leads make it ideal for both field and workshop use.
