Product Introduction
EM6910 Multifunctional Flexible Coil Large Current Clamp Meter is also known as Flexible Coil Ammeter, Roche Coil Ammeter. It is used for on-site measurement of AC current (true RMS), AC voltage, DC voltage, resistance, as well as on-off test, frequency identification, Bluetooth communication and other functions. Particularly suitable for row of dense places, thick wire cable testing, silicon controlled rectifier, frequency conversion speed control, semiconductor switch, power electronic conversion equipment, arc welding and other signals serious distortion of the industrial environment of the current test. Widely used in electric power, communications, railroads, oil fields, construction, scientific research and teaching, industrial and mining enterprises and other fields, is a necessary tool for electrician safety testing.
Flexible current clamp, i.e. RogowskiCoil (Roche Coil), is a uniformly wound toroidal coil on a non-ferromagnetic material, with no hysteresis effect, almost zero phase error, no magnetic saturation phenomenon, extremely high linearity, and strong anti-interference capability. The output signal is the differential of current to time, by integrating the output voltage signal, the input current can be realistically restored, and its measuring current range can be from milliamps to tens of thousands of amps. Flexible current clamp coil part without any bare metal conductor, non-contact measurement, safe and fast; its small size, light weight, exquisite appearance, soft and flexible, suitable for narrow environments and rows of dense places; high measurement accuracy, high reliability, wide response band, the user can be customized according to the needs of the coil length. The instrument also has an automatic shutdown function, backlight function, data retention function.
ETCRMETER is a high-end brand of ETCR. All products are manufactured by ETCR, which also provides technical support and after-sales service.
