交直流电流钳 型号PAC12
Clamp-on AC/DC current probe Model PAC12

Model PAC12 is a high precision clamp-on current probe that operates using Hall effect technology for the measurement of AC and DC currents. It has a mV BNC output so the reading can be directly displayed on an oscilloscope and comes with an automatic DC zeroing system..
