Measure spooled wire & cable sized 26 to 4/0 AWG up to 30,000 Feet in length.

1. Use an ohmmeter to measure the resistance of the length of wire. Enter the resistance & wire gauge into our free online calculator. Click here


2. Cut a length of wire, weigh it. Weigh the spool using the piece of wire you measured as your multiplier (deduct the spool weight)


3. Use the UEI CLM100 for quick and accurate readings. We keep many pre-calibrated units on hand for immediate delivery.
