Testermeter- ETCR2000C (2025) 502Ω Best Clamp on Earth ground resistance tester
Main Functions
Ground resistance, loop resistance test, grounding line leakage current test, ground fault judgment Jaw size: 55mm×32mm Resistance range: 0.010Ω~1000Ω Current range: 0.00mA~30.0A Storage function: data storage: 99 groups Alarm function: Alarm threshold can be set |
ETCR2000C clamp-on earth resistance meter, also known as clamp-on earth resistance meter, earth resistance meter, loop resistance tester, single clamp earth resistance tester, for grounding resistance, loop resistance measurement, grounding current measurement, ground fault judgment. When measuring the grounding system with a loop, there is no need to disconnect the grounding lead wire, no 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. ETCR2000C 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. |
