Rugged, compact and always reliable, the Fluke 1507 is a high accuracy insulation resistance tester with several advanced functions.
The Fluke 1507's insulation resistance mode allows the user to select between test voltages of 50, 100, 250, 500 and 1000V, giving the tester overall measurement range of 0.01MΩ to 10GΩ. Carrying out repetitive tests? The 1507 includes a Compare (PASS/FAIL) function for quicker and easier measurements.
This insulation tester is also packed full of additional features, including automatic calculation of polarisation index and dielectric absorption ratio, live circuit detection, auto capacitive voltage discharge, AC/DC voltage measurements from 0.1 to 600V and a built-in continuity testing function.
