Core Components

Hardware

Clamp-on ground resistance testers benefit from integration with Zigbee End Devices to enable real-time, low-power communication in remote site diagnostics.

Three- and four-terminal earth testers can be paired with Wi-Fi HaLow Gateways/Routers to support extended-range wireless data relay in field environments.

Soil resistivity kits and probes are enhanced by Environmental & Agriculture Sensors, providing accurate sub-surface conductivity data critical for grounding analysis.

Rechargeable or battery-powered rugged units align well with Portable Power solutions to ensure uninterrupted operation in off-grid conditions.

Large backlit LCD screens with data hold functions are supported by Display Screens that offer high visibility and durability for industrial-grade test instruments.

Case Studies

U.S. – IT Campus in California:
A large technology park near San Jose deployed our clamp-on earth resistance meters to evaluate aging ground rods in its outdoor UPS enclosures. Maintenance teams identified high-resistance joints and corrected grounding faults, significantly improving system reliability.

U.S. – Wind Farm in Texas:
Our three-pole resistance testers were used by an energy company to test ground resistance across 50 turbines. Results led to optimized electrode placement, reducing static discharge issues and equipment degradation.

Canadian – Data Aggregation Center in Ontario
A regional data services provider in Toronto leveraged our cloud-integrated grounding testers to conduct a complete ground audit. Automated reports helped satisfy regulatory inspections, and the data aided predictive maintenance planning for future system upgrades.
