AC Current Probe Model MD305

The MD305 is designed for use in industrial environments. The hook-shaped jaws enable the user to “pry” into or “hook” onto cables (will accept 2 x 500 MCM) or even smaller bus bars. It is compatible with any AC Ammeter, multimeter, or other current measurement instruments with an input impedance lower than 5Ω. It has excellent frequency and phase shift characteristics. Output termination is a double insulated 5 ft lead with safety banana plugs.

To achieve the stated accuracy, use the MD305 with an Ammeter having an accuracy of 0.75% or better.
