620LK-P5 | Intrinsically Safe Ground Continuity Tester

The AMPTEC 620LK-P5 is an affordable, highly accurate, and intrinsically safe ground continuity meter. The 620LK-P5 is very user-friendly, as it automatically reads the continuity between the earth ground and the part under test to determine if the ground is satisfactory. For use in bonding applications, including elevator tab assembly measurements, the 620LK-P5 comes from a long lineage of ultra-safe testing equipment.
