The SET500 digital earth resistance tester delivers reliable earth resistance measurement across three ranges — 20 Ω, 200 Ω, and 2000 Ω — with built-in data logging for uninterrupted field work. Part of the 500 Series, this earth ground resistance tester combines advanced functionality with economical operation, making it a practical choice for professionals who need consistent, repeatable results without overspending.
The 500 Series earth resistance test meter is designed for operational efficiency. Unlike basic testers that force trade-offs between portability and performance, the SET500 packs data logging, backlighting, and dual wiring modes into one compact unit. Whether you are conducting routine maintenance or troubleshooting a fault, this earth tester supports faster decision-making without compromising measurement integrity.
The SET500 earth ground resistance tester is suitable for a wide range of earthing verification tasks, including:
Earth resistance testing in buildings and commercial facilities
Lightning protection system checks
Remote tower and telecom site earthing
Cable earthing tests
Power transformer and equipment earthing verification
As an advanced yet economical unit, the SET500 offers a competitive earth tester price relative to its feature set. By combining three measurement ranges, data logging, and dual wiring modes in a single instrument, it reduces the need for multiple dedicated testers — delivering long-term cost efficiency for field teams and contractors.
