Measure up to 12, 120 or 1200 Amps AC (range selectable) and puts out a 100mV, 10mV or 1mV per amp AC output (1.2V full scale output) - 2.05" inside jaw diameter
Note - Some loggers can only accept 1 volt full scale input so this clamp would then only have an effective range of 10, 100 or 1000 Amps AC
