ETCR040B Power Factor Clamp Meter Of High Accuracy Clamp AC Leakage Current Sensor

Features:

ETCR040B High Accuracy Clamp Leakage Sensor is used for measurement of high accuracy AC current, leakage current, high order harmonic current, phase, power energy, power, power factor. Adopt the latest CT technology. It is portable, 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.

 ETCR040B High Accuracy Clamp Leakage Sensor’s clamp core is made of special alloy, adopt the double 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.
