MEWOI248,MEWOI248B Super-large Caliber Clamp Current Sensor is well designed and manufactured for measurement of AC current, higher harmonic current, phase, electric energy, power and power factor, by adopting the latest CT technology. Its large caliber 148mm×108mm can clamp electric cable of Φ108mm, or 160mm×4mm flat cable and steel earth wires. It is portable, clamp designed, no need to disconnect the circuit, non-contact measurement, which means safer and faster. It can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, electric power quality analyzer, high precision multi-meter, widely applied in those fields as electricity, communications, meteorology, railroad, oilfield, construction, measurement, scientific & research teaching institutes, industrial and mining establishments.

The clamp is made of special alloy, adopt the latest CT and magnetic shielding techniques, can almost shield the influence from external magnetic field, to ensure the high precision, high stability and high reliability of perennial uninterrupted measurement
