Product introduction
Musktool-ETCR6920B flexible high-current clamp meter is carefully developed by our company and is carefully designed and manufactured for field testing of AC high current. It can also be used as an ordinary multimeter to measure AC voltage, DC voltage, resistance, on-off test, etc. Widely used in electric power, communications, meteorology, railways, oil fields, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. It is especially suitable for places with dense wiring, transformer core current test against the wall, thick wire cable test, relay protection, thyristor rectification, frequency conversion speed regulation, semiconductor switch, power electronic conversion equipment, arc welding and other places where the signal is seriously distorted. Current testing in industrial environments. The flexible current clamp , namely Rogowski Coil (Rogowski coil), adopts advanced Rogowski coil technology, which is a toroidal coil uniformly wound on non- ferromagnetic materials , without hysteresis effect , almost zero phase error, no magnetic saturation phenomenon, linear High accuracy, strong anti-interference ability. The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The measured current range can range from milliamps to tens of thousands of amperes. The coil part of the flexible current clamp does not have any exposed metal conductors, non-contact measurement, safe and fast; it is small in size, light in weight, beautiful in appearance, soft and flexible, suitable for narrow environments and places with dense wiring; high measurement accuracy, strong reliability, The response frequency is wide, and users can customize the coil length according to their needs. Musktool-ETCR6920B flexible high-current clamp meter is small in size and light in weight. It is very light and simple to operate on site and has high measurement accuracy. The instrument has a USB communication interface and can store data. Upload the stored data to the computer through the system software to realize reading, querying and saving of historical data. , printing and other functions. The instrument also has a backlight function and a data retention function, which is an essential tool for electrician safety testing. |
