FLUKE Insulation Tester, 203 (L) x 100 (W) x 50mm (D), 1000h Battery Life - 2491945

Want to make short work of electrical maintenance? Get the job done safely and efficiently with this FLUKE insulation tester. By measuring resistance across a device, it quickly identifies faulty insulation to catch leakage current before it turns hazardous. As the unit comes with voltmeter and ammeter functions, it tackles many electrical tests in one go to help you speed through servicing tasks. Testing in dim lighting is a breeze, thanks to the backlit digital display. The tester's output voltages between 50 and 1000V mean it adjusts to handle different circuits at the flick of a switch.

Features & Benefits

• Best resistance measuring accuracy of ±0.9% + 2 counts to ensure precise readings
• IP40-rated casing protects against objects larger than 1mm, such as tools and wires, for safe handling
• Labelled dial and push button controls for handy navigation of settings
• Live voltage alerts to cut exposure to dangerous electrical loads
