SL180ACable outer protective ring current grounding tester
In order to meet the measurement needs of grounding current, our company has developed an anti-interference cable outer sheath ring current grounding tester product.SL180A Cable Outer Sheath Ring Current Grounding TesterAdopting a brand new digital circuit, it has the characteristics of high efficiency, small size, and light weight. Select the latest specialized current clampCT double-layer magnetic shielding technology and zero input impedance current measurement technology are almost unaffected by external magnetic and electric field interference, ensuring high accuracy, stability, and reliability of data acquisition and measurement. The handheld host is controlled by an ARM processor and automatically completes functions such as self checking, data processing, and waveform display.
SL180A Cable Outer Sheath Ring Current Grounding TesterIt is also applicable to current, harmonic, and leakage current testing of lines or equipment in fields such as communication, meteorology, railways, oil fields, construction, metrology, scientific research and teaching units, and industrial and mining enterprises.
