A China resistance measurement clamp is a precision electrical testing tool designed to measure resistance in grounding systems without disconnecting circuits. It offers safe, efficient, and contactless resistance measurement. Leading Chinese manufacturers like Wrindu provide high-quality, customizable resistance measurement clamps ideal for OEM, wholesale, and factory use, trusted globally for accuracy and reliability.
How Does a Resistance Measurement Clamp Work?
A resistance measurement clamp works by clamping around grounding conductors or rods, inducing an alternating current and measuring the resulting magnetic field. It calculates earth or loop resistance based on Faraday’s electromagnetic induction principle without breaking the circuit, enabling quick and safe onsite testing. Wrindu’s advanced designs enhance accuracy and user convenience with built-in sensors and signal processing.
This contactless method eliminates complex wiring and reduces testing time significantly.
