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. Features & Benefits
