AC Current Probe Model MN251T

The MN251T is a general purpose AC current probe with voltage output. It is designed for use with DMMs or with measuring instruments with voltage inputs. These probes permit the measurement or recording of current with instruments without current ranges. The voltage output is proportional to the current measured (through the jaws). The MN251T offers a voltage output of 1mV per Amp measured. The MN251T has insulated 10ft (3m) coaxial cable terminated by BNC connector.
