The loop resistance tester, also known as the contact resistance tester, is called Loop Resistance Tester in English. According to the requirements of the new "Power Equipment Handover and Preventive Test Regulations", the measurement of the conductive circuit resistance of various switchgear must use a test current of no less than 100A.

Loop Resistance Tester: Purpose and application scope of the ground resistance meter: The ground resistance meter is suitable for directly measuring the ground resistance value of various grounding devices, and can also be used for general low resistance measurements. The four-terminal (0-1-10-100Ω specifications) can also measure soil resistivity. Loop Resistance Tester: Single-clamp loop resistance tester

Performance and features of the single-clamp loop ground resistance tester: Unique single-clamp design avoids errors caused by mutual interference between the two probes of a double-clamp type. No auxiliary ground rods are needed; just clamp it directly to measure.

Loop Resistance Tester: Universal ground/insulation resistance tester

There are many testing methods: double-clamp ground resistance test, four-pole ground resistance test, soil resistivity test, insulation resistance test, AC/DC resistance tester voltage test, and current RMS test.

Loop Resistance Tester: Ground impedance tester

When measuring with the clamp-type ground resistance meter series, there is no need to use auxiliary ground rods, nor to interrupt the grounding of the equipment under test. Just clamp the ground wire or rod to measure the ground resistance up to 0.1Ω. It can also perform current measurement.

Microprocessor controlled, with high precision and high reliability. Three indicator lights check whether the wiring status is correct. Directly read short-circuit protection current and ground fault current. Automatically locks when the test resistor overheats.

Loop Resistance Tester: Digital ground resistance tester

This tester is specially used to measure the ground resistance value of various electrical equipment, lightning rods, and other grounding devices. The product is an all-electronic instrument, and the key circuits are assembled from integrated circuits produced by Texas Instruments in the United States. The testing principle is advanced.

Loop Resistance Tester: Double-clamp ground resistance tester

It has multiple ground resistance measurement methods: no auxiliary electrode / three-pole / four-pole / two-pole method - suitable for various measurement environments, with a wide measurement range: 0.002Ω to 300KΩ - meeting various requirements.
