Product details
Large caliber clamp leakage current meter clamp leakage current meter clamp current meter model: HAD-ETCR7100
The HAD-ETCR7100 ultra large caliber clamp type leakage current meter is carefully designed and manufactured for measuring AC leakage current and current. It adopts CT technology and digital integration technology. The ultra large caliber (108mm × 148mm) can clamp either a φ 108mm cable or a 160mm × 4mm flat steel ground wire, making it particularly suitable for cable leakage and transformer grounding flat steel leakage detection. It is fully automatic, LCD display, clear at a glance, convenient and fast. Widely applicable to fields such as electricity, communication, meteorology, railways, oil fields, construction, metrology, scientific research and teaching units, industrial and mining enterprises, etc.
The HAD-ETCR710 ultra large caliber clamp type leakage current meter uses a special alloy for the clamp head iron core and adopts magnetic shielding technology, which reduces the influence of external magnetic fields and ensures high accuracy, stability, and reliability for uninterrupted measurement throughout the year. The instrument has an RS232 interface and can store 99 sets of data. The stored data can be uploaded to the computer through the system software for easy reading, saving, printing and other functions of historical data. The instrument also has backlight function and data retention function, making it an essential tool for electrical safety testing.
