Advanced Stakeless Ground Testing with Certified Accuracy
The REED Instruments R5710-NIST is a high-performance clamp-on tester designed to simplify the measurement of ground resistance in multi-grounded systems.
By utilizing a specialized induction method, the R5710 allows you to measure resistance without the need for auxiliary ground stakes or disconnecting the ground rod from the system. This model includes an NIST-Traceable Calibration Certificate, providing the verifiable accuracy required for high-stakes electrical inspections, utility maintenance, and lightning protection audits.
Key Technical Advantages
-
Stakeless Measurement Technology: Quickly measure ground resistance from 0.01Ω to 1500Ω simply by clamping onto the ground conductor, significantly reducing time spent in the field.
-
Leakage Current Detection: Beyond resistance, this versatile tool measures AC leakage current from 0.00mA to 40.0A, helping you identify potential system faults or grounding issues.
-
Large Jaw Capacity: The 1.25" (32mm) jaw diameter accommodates large ground conductors and bus bars found in industrial and utility settings.3
-
Data Logging & Alarms: Store up to 99 sets of data in the internal memory and utilize the user-programmable High/Low alarms for rapid "Pass/Fail" field testing.
-
Safety & Documentation: Ships with a NIST-traceable certificate with full data and uncertainties, ensuring compliance with strict industrial safety standards and insurance requirements.
Ideal Applications for the REED R5710
-
Telecommunications Grounding: Verify the integrity of grounding systems for cell towers and central office equipment.
-
Electrical Utilities: Test ground resistance for utility poles, transformers, and sub-station grounding grids.
-
Lightning Protection Systems: Ensure that commercial and residential lightning rods have a low-resistance path to earth.
-
Industrial Maintenance: Conduct periodic grounding audits in manufacturing plants to prevent equipment damage and ensure worker safety.
-
Leakage Current Monitoring: Identify ground loops and low-level current leakage in complex electrical distributions.
