Feature: 1. Good practicability, it is suitable for the detection of AC and DC current, phase, electric energy, power, power factor, etc., and is widely used in the power industry. 2. Adopting Hall induction technology, it is not necessary to disconnect the tested circuit during detection, and the clamp head iron core is made of special alloy, which is especially suitable for places with dense wiring (electricity metering system, high speed rail system, automobile circuit maintenance, etc.). 3. Supports collocation use, it can be connected to phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, digital multimeters, etc. 4. Using permalloy iron core and magnetic shielding technology, it has stable performance, high accuracy, strong anti interference ability, and the data can reach high industrial standards. 5. Using a split core and a hole element (hole element) combination, it can simultaneously detect AC and DC current, which can help you save time and effort, and improve the efficiency of detection.
