ETCR7100 Superlarge Caliber Leakage Clamp Meter AC 0.0mA-3200A \ RS232 \ Data Storage

 ETCR7100 Superlarge Caliber Leakage Clamp Meter is well designed and manufactured for measuring AC leakage current, current, voltage, adopt the latest CT technology and digital integrated technology. Its large caliber 108mm×148mm can clamp electric cable of 108mm diameter, or 160mm×4mm flat cable and steel earth wires. It has the biggest caliber and widest current range all over the world, particularly suitable for leakage current measurement of cable and transformer earth steel. Full automatically and LCD display, all the data are displayed in the screen, which is very clear and convenient. The meter is widely used in electric power, communication, meteorology, railway, oil field, architecture, measuring, teaching research unit, industrial mining enterprises, etc.

   ETCR7100 Superlarge Caliber Leakage Clamp Meter’s clamp core is made of special alloy, adopt the latest magnetic shielding techniques, to ensure the high precision, high stability and high reliability of perennial uninterrupted measurement. The meter can store 99 sets of data, with RS232 interface, upload stored data to the computer through the system software, implementing online real-time monitoring, historical inquires, dynamic display. With the function of historical data read, export, print, and backlight, data hold, etc. It is a necessary tool for electrical safety testing.
