British Standard BST-BT751 Insulation Resistance Tester with Voltage Measurement Function
BST-BT751 is a portable insulation resistance tester designed specifically for electrical installation personnel to measure insulation resistance. It can measure voltages up to 1000VDC and 600V, and perform continuity tests on grounding conductors. It is suitable for both civilian and industrial electrical environments.
Other special features include LOCK lock function, adjustable timer, and a large LCD backlit display screen. The LOCK locking function can perform continuous insulation measurement on the tested equipment. The adjustable timer from 2s to 60s allows users to decide the duration of the measurement, and its large LCD display with backlight function allows users to work in weak/dim light environments.
