Feature: 1. Clamp leakage current sensor uses the latest CT technology and digital integration technology to measure AC/DC current and leakage current under 600V line voltage. 2. This small clamp is suitable for densely populated areas (electric power measurement system, high‑speed rail system, automatic circuit maintenance, etc.), non‑contact measurement ensures safe operation. 3. It is small in size, high in accuracy and stable in performance. It can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, electric power quality analyzer and high‑accuracy multimeter. 4. The sensor is widely used in electric power, communication, meteorology, railway, automobile industry, oil field, construction, measurement, scientific research and education institution, industrial and mining enterprise and other fields. 5. The input range is 0mA‑60.0A AC/DC and the resolution is 1mA AC/DC, which is easy to operate and convenient to use. Made of high‑quality material, it is not easy to damage, durable and has a long service life.
