The loop resistance tester, also known as contact resistance tester, English name: Loop Resistance Tester. Detailed introduction according to the new "Power Equipment Handover and Preventive Test Procedures" requirements, the measurement of conductive circuit resistance of various switchgear, the test current shall not be less than 100A.

Loop resistance tester: Ground resistance meter purpose and scope of application: Ground resistance is suitable for direct measurement of grounding resistance values of various grounding devices, and can also be used for general low resistance measurement. Four-terminal (0~1~10~100Ω specifications) can also measure soil resistivity. Loop resistance tester: Single-clamp loop resistance tester

Single-clamp loop ground resistance tester performance and features: Unique single-clamp design, can avoid the error of mutual interference between two probes of double-clamp type. No need to drive auxiliary ground rods, just clamp it to measure.

Loop resistance tester: Universal ground/insulation resistance tester

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

Loop resistance tester: Ground impedance tester

When measuring with the clamp-type ground resistance meter series, it is not necessary 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 resistance to ground 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 grounding resistance value of various electrical equipment, lightning rods and other grounding devices. The product is an all-electronic instrument, and the key circuit is assembled with integrated circuits produced by Texas Instruments, USA. The test principle is advanced.

Loop resistance tester: Double-clamp ground resistance tester

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