Duratool Limited 1000V Digital Insulation & Continuity Tester

The Duratool Limited 1000V Digital Insulation & Continuity Tester is a professional-grade multifunction instrument designed for demanding electrical testing scenarios. It combines comprehensive insulation testing capabilities with essential multimeter functions, providing a versatile tool for diagnosing electrical systems safely and accurately.

A standout feature is its ability to perform insulation tests at multiple standard voltages: 50V, 100V, 250V, 500V, and 1000V. It measures insulation resistance across an impressive range from 10kohm to 10Gohm, making it suitable for everything from low-voltage circuitry to high-voltage installations. The instrument automatically calculates Polarisation Index (PI) and Dielectric Absorption Ratio (DAR), key metrics for assessing the health of electrical insulation.

For operator safety and convenience, it includes an auto-discharge function for capacitive loads and a safety rating of CAT III 1000V and CAT IV 600V. Additional practical functions include timer and lock features for automated insulation testing, a store/load and compare function for tracking results, and low-battery indication. The tester also performs standard AC/DC voltage and continuity tests.

Housed in a robust carry case, the unit is powered by six AA batteries (not supplied) and is built for reliability in commercial and industrial environments. Its clear functionality and safety-focused design make it an indispensable tool for precise electrical measurement and maintenance.
