Musktool- ETCR2000(2025) 500Ω Best Clamp on Earth ground resistance tester
ETCR2000 Clamp Ground Resistance Meter, also known as Clamp Ground Resistance Meter, Ground Resistance Meter, Loop Resistance Tester, Single Clamp Ground Resistance Tester, is used for grounding resistance, loop resistance measurement, and ground fault judgment. In the measurement of the grounding system with a loop, without disconnecting the grounding lead, without the need for auxiliary grounding pole, safe and fast, easy to use. Clamp grounding resistance meter is widely used in electric power, telecommunication, meteorology, oil field, construction and industrial electrical equipment, grounding resistance measurement, circuit resistance measurement. The long jaw is especially suitable for flat steel grounding place. ETCR2000 can measure ground faults that cannot be measured by traditional methods, and can be applied to occasions that cannot be measured by traditional methods, because the clamp-on earth resistance meter measures the combined value of grounding body resistance and grounding lead resistance. |
Product features
1, non-contact measurement of safety and speed, in the measurement of the grounding system with a circuit, without disconnecting the grounding lead, without the need for auxiliary grounding pole, saving time and effort. 2,Clamp grounding resistance meter can measure the ground fault which can not be measured by traditional methods, and can be applied to the occasions which can not be measured by traditional methods. 3, keep function, storage function, storage data 99 groups. 4, alarm function, can set the alarm threshold. |
