ETCR7000B Large Caliber Leakage Clamp Meter

ETCR7000B series of Large 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 80mm×80mm can clamp electric cable of 80mm diameter, or 96mm×4mm flat cable and steel earth wires. Full automatically and simultaneously measure one leakage current and three voltages, 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.
ETCR7000B series of Large Caliber Leakage Clamp Meter’s clamp core is made of special alloy, adopt the latest 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. The meter can store 200 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.
