Examine your circuit protection devices for efficiency with this loop impedance and RCD combined tester from Megger. It checks your loop systems, measuring the resistance of electrical loads and safety components like fuses and breakers to find high-resistance connections. The unit also assesses the trip time and sensitivity of your RCD to ensure it reacts quickly to leakage faults. Thanks to non-trip testing, you can monitor your live network without setting off ≥30mA RCDs, which prevents downtime. A backlit display means you won't miss a thing, even when you're working in dark spots.

• Auto-start function improves safety by kicking off the test immediately after you connect the leads
• Wide operating voltage range between 50 and 440V AC for versatile use
• Automatic noise detection and test extension to ensure accurate results
• Built-in front cover for impact protection in harsh environments

• Audiovisual installations
• Oil and gas plants
• Marine engineering

This unit weighs just 1kg excluding the test leads, so it's easy to transport when going about your work.
