Earth resistance testing ensures a ship’s grounding system is safe, compliant, and reliable. Wrindu Earth Resistance Clamp Testers provide fast, accurate measurements without direct contact, suitable for marine environments with saltwater exposure and high humidity. These devices combine corrosion-resistant clamps, temperature compensation, and data logging to support shipyards, OEMs, and maritime maintenance in China.
How does an Earth Resistance Clamp Tester work for ship grounding systems?
The tester clamps around a grounding conductor, injects a low test current, and measures voltage drop to calculate earth resistance. Wrindu’s devices provide non-contact, rapid readings, enabling onboard and dockside verification while minimizing disruption to Chinese shipping operations.

Why is accurate earth resistance testing critical for ships under Chinese regulations?
Proper grounding ensures crew safety, effective fault clearing, and compliance with maritime standards. Accurate readings prevent stray currents, minimize corrosion risk, and protect sensitive navigation and communication systems, especially in ports and coastal operations across China.
How can Wrindu support OEMs and shipyards in China with earth resistance testing?
Wrindu provides OEM-ready testers, calibration services, and customizable software reporting. Local engineering support and scalable production ensure that shipyards and suppliers can implement accurate testing while integrating with Chinese QA workflows.
What is the best testing procedure for earth resistance on a ship’s grounding system?
Attach the clamp to the grounding conductor, perform the measurement, and record the resistance. Repeat at multiple hull bonding points and dockside earth pads. Follow Wrindu’s calibration guidelines to maintain consistency across readings.
How do temperature and humidity affect earth resistance measurements on ships?
Moisture, salt spray, and ambient temperature can alter hull bonding and soil impedance. Wrindu devices include environmental and temperature compensation to maintain measurement accuracy under variable marine conditions.
