Waco Four Terminal Single Range Earth Tester is a precision instrument tailored for measuring earth resistance in installations where a single range is sufficient. It uses a four-terminal method to ensure highly accurate measurements by minimizing lead resistance errors. Housed in a durable casing, it’s ideal for field work across rural and industrial settings. The analog scale is well-calibrated, and its mechanical robustness makes it a go-to device for quick, repeatable results in earthing system validation. Recommended for electrical contractors and site engineers engaged in grounding checks on small to medium installations.

Available on EnvMart, these Resistance Meters are perfect for accurately measuring electrical resistance in circuits and components. Waco Resistance Meters provide precision and reliability, making them ideal for professional electricians and laboratory use.
