Feature: 1. The 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 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 precision and stable in performance. It can be connected with phase detection analyzer, industrial control equipment, data logger, oscilloscope, electrical power quality analyzer and high precision multimeter. 4. The sensor is widely used in electric power, communication, meteorology, railway, automobile industry, oil field, construction, measurement, scientific research and educational institution, industrial and mining enterprises 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.
