ETCR7100D Super Large Caliber DC/AC Clamp Meter
ETCR7100D Super Large Caliber DC/AC Clamp Meter


ETCR7100D Super Large Caliber AC/DC Clamp Meter is well designed and manufactured for measuring AC/DC current below 600V line Measure, it adopt the latest CT technology and digital integrated technology. No exposed metal conductor in the Clamp and no-contact measure model mean current measure operation more safer and quicker. Super large Caliber is  particularly suitable for thick wire current measure. This meter is widely used in electric power, communication, meteorology, railway, oil field, architecture, measuring, teaching research unit, industrial mining enterprises, etc.
The instrument with current peak value holding, data holding, data storage and other function. Equipped 

With USB interface, communication line and supervision software, this meter could achieve current online monitoring, show the real time current condition via computer, with consult historical data, saving, print and other functions.
