OneETCR2100A+Clamp type grounding resistance meterIntroduction
ETCR2100A+Clamp type grounding resistance meterWidely used for measuring grounding resistance and loop resistance in power, telecommunications, meteorology, oil fields, buildings, and industrial electrical equipment. When measuring a grounded system with a circuit, there is no need to disconnect the grounding lead or auxiliary power, which is safe and fast. It can measure grounding faults that cannot be measured by traditional methods, and can be applied to situations where traditional methods cannot measure. It measures the comprehensive value of grounding body resistance and grounding lead resistance.
ETCR2100A+Clamp type grounding resistance meterThis is another upgrade of our company's old product. Performance comparison between the new and old products:
| project | ETCR2100 (old model) | ETCR2100+(new model) |
| product appearance | ![]() | ![]() |
| boot time | Self check takes 6 seconds, and a long startup time can easily cause startup errors. | Self check only takes 0.5 seconds and is completed instantly upon startup. |
| measurement range | 0.01-1000Ω | 0.01-1200 Ω, wider range. |
| store data | 30 groups | 99 groups |
| buzzer alarm | Nothing | have |
| interference recognition | Nothing | There are buzzing and flashing Noise symbols, with strong anti-interference ability. |
| 232 interface | Nothing | Can connect to RS232 interface |
| power waste | Large 100mA | Larger 50mA, longer battery life. |
| Instrument appearance | The machine is bulky, rough in appearance, and difficult to operate. | The appearance is delicate and beautiful, the structure is more sturdy, and the operation is comfortable. |
| Battery cover plate | Without fastening screws, it is easy to cause battery detachment and potential accidents. | There are fastening screws, which are safe and reliable, and the battery is easy to replace. |
