MEWOI1000 H/L Voltage Clamp Meter has unique features of automatic plug function, specially designed and manufactured for high voltage current measurement; use the latest CT technology and integrated mask digital technology; composed of special high voltage detector, wireless receiver and high voltage insulation rods. Wireless transmission can receive the measured data by penetrating storey building barriers or 300 meters. If not use insulated rods, it can also used as high-precision low-voltage clamp meter and leakage current meter, can accurately measure the 0.0mA ~1000A current or leakage current.  

      The integrated design of clamp and lead zone of MEWOI1000 H/L Voltage Clamp Meter ensures uninterrupted year-round high precision, high reliability and high stability test. 

The connection rods of MEWOI1000 wireless high and low voltage clamp ammeter can be applied in high voltage line current measurement and online current measure below 60KV, also with the functions of peak value maintaining, data maintaining, data memory, etc. The special clamp ammeter can facilitate clamp to exit the tested lead by pressing or pulling back insulation bar, which is time efficient and convenient; widely used in power plant, substation, industrial and mining enterprise, inspection station, electrician maintenance department for current sensing and field working. It can also be used as high and low voltage changing ratio tester, that is, respectively test the first loop and secondary loop high and low voltage current, and then obtain the voltage change through manually calculation. Insulation rod has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation and scalability, etc.
