AC current probe PT-721
1.1200A height linear measurement, uniformly distributed coil, magnetic element excitation adjustment system, clamping of a ø 52mm conductor, micro metal coil suitable for power meters.
2. With insulated BNC coaxial cable, it can be used in conjunction with any multimeter, ammeter, recorder, oscilloscope, etc., making it easy to display and measure current waveforms, and output mV signals. It has three ranges and is an OEM brand for products such as A621 and i1000s.
