The Fluke 1625-2 is a ground tester engineered for versatility and precision, enabling four distinct measurement techniques in one compact unit. It accommodates both traditional stake-based methods—delivering reliable 3- and 4-pole fall-of-potential and 4-pole soil resistivity assessments—and innovative clamp-based approaches, including selective testing with a single clamp combined with stakes and a stakeless option using two clamps exclusively. Designed with efficiency in mind, its adjustable testing limits allow for quicker and more tailored evaluations.
