Extech Instruments announces the new 382252 Earth Ground Resistance Tester Kit. For new installations and predictive maintenance inspections in industrial and commercial settings, the 382252 measures earth ground resistance in three ranges of 20Ω, 200Ω and 2000Ω, earth voltage up to 200 Vac and resistance up to 200kΩ, as well as ac and dc voltage, up to 750V and 1000V, respectively.
Enclosed in an ergonomic rubber holster, the rugged new tester offers one-button testing, easy-to-read dual display, HOLD function, automatic zeroing, a Category III-1000V overvoltage rating and a measuring frequency of 2.5 times samples per second.
The new earth ground tester kit is designed for quick and accurate testing with an existing ground and two ground-stake earth bars (included). Earth ground resistance tests are essential for installation of new grounding systems and electrical equipment; antenna tower construction and maintenance (PCS, cellular, microwave, short-wave, meteorological, broadcast radio or television), earth ground system design; routine testing of ground and lightning protection equipment; and the installation of transformers, switchgears, machines and other electrical equipment.
The tester kit comes equipped with test leads, two auxiliary ground-stake earth bars, carrying case and batteries.
