The model 310 Digital Milli-Ohm Meter is used

to ensure continuity and integrity of a wire,

cable, conduit or any electrical connection. The

310 has a display resolution of 100 micro-ohms

and has a professional four wire Kelvin test lead

set included to ensure accurate readings. The

heavy duty case has a rubber seal to make the

unit water resistant and a convenient shoulder

strap.
