AC High Voltage Clamp Meter

HCL-36UX Digital Clamp Current Tester for Middle Voltage

1, No need to clamp on the overhead distribution line up to 36kV for load current measurement.
2, Max 25th order Harmonics current measurement by using our APP without cut the insulation layer.
3, Structure resistant to drop impact.


・Display measurement value on your smartphone through blue-tooth connecting.
・Measurement value can be kept in the our cloud server.
・In addition to measured values, location registration by GPS, temperature, date and time can also be saved.
