Check your wiring is up to scratch with this two-in-one insulation tester from FLUKE. It's a versatile instrument that measures insulation resistances between 0.1 and 600MΩ and lets you select either 500 or 1,000V test voltages to suit your application. As it also works as a multimeter, additional resistance and continuity functions enable you to carry out quick circuit checks. The device comes with true-RMS functionality, meaning it detects both sinusoidal and non-sinusoidal waveforms to ensure your AC measurements are spot on. It has a large backlit digital display, so you can easily read your results even in low-light conditions.

• Comes with remote probe, test leads and alligator clips, so it's ready to go straight out of the box
• Long battery life lets you complete 1,000 tests without stopping
• Auto-off feature saves power, making it an energy-conscious option
• Rugged case helps protect your instrument from bumps and scratches in the field

• Motor maintenance
• Plant machinery
• Telecommunications industry

This insulation tester meets the CAT III 1000 V and CAT IV 600 V standards, so you can rest assured it safely handles heavy-duty applications.
