Using zero flux technology (Hall element) current sensor, dual range design covers small to large current, accurate observation of current waveform. Whether the current fluctuation of the high-efficiency switching device, the current of the power-saving device as low as 1mA, or the high-speed transient current of the power-on, it can be handled. Excellent frequency response ability, can analyze and display the current waveform containing multiple frequency components, such as switching frequency, pulse waveform, etc., so as to meet the comprehensive measurement needs of complex current signals.

Advanced high-frequency current probeDirectly connected to domestic models such as Puyuan/Dingyang/Unilead, BNC direct connection eliminates the impedance matching problem. The plug-and-play architecture adapts to the mixed use of multiple devices in teaching laboratories, and the efficiency of student training is significantly improved. |
Intelligent jawsThe ∅5mm jaws are designed for precision current measurement in tight spaces. Its core highlight is the intelligent status indication function: when the jaws are not fully pushed to the bottom and locked, the probe will automatically light up a striking red light to ensure that the operation is correct before each measurement, effectively eliminate the measurement error or safety hazards caused by the jaws not closed, allow engineers to quickly confirm the status of the equipment, and improve measurement efficiency and reliability. |
