Earth & Leakage Testers

Small leakage currents can trigger protective devices, waste energy or indicate deteriorating insulation long before equipment fails completely. The Fluke 368 FC True-RMS Leakage Current Clamp Meter detects and trends these low-level currents without taking equipment offline. It offers resolution down to 1 µA...

Complex installations containing connected electronics, surge-protection devices and modern RCDs require more protection and diagnostic capability during certification. The Fluke 1674 FC Multifunction Installation Tester is the top model in the 1670 Series, adding Insulation PreTest and SPD insulation ramp testing to the connected...

Modern installations increasingly include DC-sensitive protection, EV charging equipment and digital reporting requirements. The Fluke 1673 FC Multifunction Installation Tester expands the 1670 Series with wireless connectivity and advanced protection-system testing. It provides insulation test voltages from 50 V to 1000 V, continuity, loop...

Installation testing can become slow when every measurement requires separate setup and manual interpretation. The Fluke 1672 Multifunction Installation Tester introduces Fluke's newer 1670 Series workflow with a full-colour touchscreen, simplified user interface, Auto Test and automatic measurement validation. The 1672 supports AC/DC voltage...

Routine fixed-wiring verification requires several essential measurements, but not every installation technician needs advanced earth testing or wireless reporting. The Fluke 1662 Multifunction Installation Tester provides the core functions needed for basic domestic, commercial and industrial installation testing. It performs insulation-resistance and continuity testing,...

You can't properly evaluate a grounding system with a single test method in every installation. The Fluke 1623-2 GEO Earth Ground Tester supports four established approaches: 3- and 4-pole fall-of-potential, 4-pole soil resistivity, selective testing and stakeless testing. This flexibility allows technicians to test...

Leakage-current testing becomes difficult when multiple conductors or larger cables cannot fit through a standard leakage clamp. The Fluke 369 FC True-RMS Leakage Current Clamp Meter provides the same high-resolution diagnostic capability as the 368 FC but adds a larger 61 mm jaw for...

Earth-ground testing can become difficult where pavement, buildings or operating installations prevent the use of auxiliary ground stakes. The Fluke 1630-2 FC Earth Ground Clamp Meter measures earth-ground loop resistance on suitable multi-grounded systems without disconnecting the electrode or driving test stakes. Its dual-clamp...

Ground measurements near substations, industrial equipment, or electrically noisy environments can be affected by interference, making stable results harder to obtain. The Fluke 1625-2 GEO Earth Ground Tester adds advanced measurement control to Fluke's multi-method ground-test platform. It supports fall-of-potential, soil resistivity, selective and...
