NEWTRY 0.01~200Ω Ground Earth Resistance Clamp Tester, Digital Ground Resistance Tester, for Electric Power Telecommunication Meteorology Oilfield Construction, Case Included

The tester can be used for the grounding resistance measurement of electric power, telecommunication, meteorology, oil field, construction and industrial electrical equipment. When measuring a grounding system with a return circuit, there is no need to disconnect the ground wire and no auxiliary electrode is required. The clamp-on grounding resistance meter can measure the ground fault that cannot be measured by traditional methods, and can be applied to the occasions that cannot be measured by traditional methods, because the clamp-on grounding resistance meter measures the combined value of the grounding body resistance and the grounding lead resistance. Clamp size: 2.17"*1.26" Resistance measuring range: 0.001-200Ω Resolution: 0.001Ω Accuracy: ±(1%+0.01Ω) Operating temperature: 14℉-131℉ Relative humidity: 10%-90% LCD display: 1.85"*1.12" Protection level: Double insulation External electric field: <1V/m Single word measurement time: 1 second Measured current frequency: 50/60Hz Measurement data storage: 99 sets Resistance alarm critical value setting range: 1-199Ω

• [Main Parameters]: Measuring range: 0.01~200Ω. Accuracy: ±1%. Resolution: 0.001Ω. Resistance measurement frequency: >1kHz. External magnetic field: <40A/m. External electrical field: <1F/m. Measured current frequency: 50/60Hz automatic. Single measurement time: 1 second. Data storage: 99 sets. Alarm threshold setting range: 1-199Ω. Clamp table size: 10.82*3.34*2.20 inches. Clamp size: 2.16*1.25 inches.
• [Safer]: This clamp-on ground resistance tester is equipped with a large 2.16*1.25-inch jaw. The design of double insulation of this tester can effectively protect your safety. In addition, this meter will automatically adjust its own range during measurement.
• [Light Alarm Function]: This ground resistance tester comes with a light warning function. You can set the threshold value, when the measured value exceeds the threshold value, the screen will automatically flash to remind you. The setting range of resistance alarm threshold is 1-199Ω.
• [Easy to Use]: This ground resistance tester has an automatic calibration function and can be tightly closed without gaps, so it can effectively reduce magnetic field induction errors. The data storage function of this tool can store up to 99 sets of measurement data, which is more convenient for your work.
• [Wide Application]: The tester can be used for the grounding resistance measurement of electric power, telecommunication, meteorology, oil field, construction and industrial electrical equipment. When measuring a grounding system with a return circuit, there is no need to disconnect the ground wire and no auxiliary electrode is required.
