ETCR068B Clamp current sensor

I.Brief introduction

ETCR068B Clamp Current Sensor is used for measurement of AC current, AC leakage current, high harmonic current, phase, power energy, power, power factor. Adopt the latest CT technology. It is portable, large clamp design, no need to disconnect the measured circuits, non-contact, safe and fast. It can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, harmonic analyzer, electric power quality analyzer, high precision digital multi-meter, etc. Widely applied in electricity, communication, meteorology, railway, oilfield, construction, measurement, scientific and research teaching unit, industrial and mining enterprises.

ETCR068B Clamp current Sensor’s clamp core is made of special alloy, adopt 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. It suitable for AC current, harmonic current, phase, power energy test.
