Professional Grade Clamp Ground Resistance Tester, Earth Ground Meter with Current Measurement, Data Storage, Alarm for Power Systems, Telecom and Industrial Use 0.01-500Ω

The VIVANTECH Clamp Ground Resistance Testers are advanced, easy-to-use instruments designed for professionals who need to quickly and accurately measure grounding resistance and leakage current without disconnecting ground leads. Whether you're working in power distribution, telecommunications, or building lightning protection, these meters provide reliable results in both multi-point and single-point grounding systems. How It Works: Using a clamp-on design with integrated voltage and current coils, the meter induces a test signal into the ground loop and calculates resistance based on the measured voltage and current. This method eliminates the need for auxiliary ground rods and disconnecting down conductors—saving time and improving safety. Key Features at a Glance: Measures ground resistance from 0.01Ω to 500Ω with auto-ranging Stores up to 99 data sets with recall function Adjustable alarm threshold for pass/fail testing Large LCD with backlight and clear symbols for battery, data lock, and clamp status Comes with test ring, meter case, and user manual Ideal For: Electrical contractors and maintenance technicians Utility and telecom field engineers Lightning protection system inspectors Industrial and commercial facility safety audits What’s Included: 1 x Clamp Ground Resistance Tester 1 x Test Ring (5.1Ω for calibration check) 1 x Carrying Case 1 x User Manual 1 set of Batteries Note: Always follow safety guidelines when using electrical test equipment. Do not measure live power lines. For best results, ensure clamp jaws are clean and properly closed before each use. Upgrade your grounding testing toolkit with the VIVANTECH Clamp Ground Resistance Tester—designed for accuracy, built for durability, and trusted by professionals.

• 🔧 Accurate Ground Resistance & Current Measurement. This clamp-on ground resistance tester measures resistance from 0.01Ω to 500Ω and AC current up to 20A (DY3000A) with high precision. Ideal for grounding system diagnostics in power, telecom, and lightning protection applications.
• ⚡ Non-Contact Clamp Design for Safe & Easy Use. No need to disconnect ground leads or use auxiliary rods. Simply clamp around the ground conductor or test wire for quick, safe, and reliable measurements—perfect for both multi-point and single-point grounding systems.
• Data Storage & Adjustable Alarm Function. Store up to 99 groups of measurement data for later review. Set custom alarm thresholds for resistance or current, and receive visual alerts when values exceed limits—ideal for routine inspections and troubleshooting.
• Versatile Field Applications. Suitable for measuring tower grounding, transformer neutral points, substation grounding, telecom room grounding, and building lightning protection systems. Also supports two-point and three-point methods for isolated grounding electrodes.
