ALLOSUN Digital Cable Length Multimeter Wire Gauge Phone LAN Network Tracker Tester Temp Ohm Resistance Meter

Seems be very accurate. The Pre-set wire sizes are in mm, not AWG. The user defined settings are fairly easy to calibrate to any size. All in all, an awesome tool that is a HUGE labor and material saver!!!

I thought that the precise measurements would relate to AWG but they are in centimeters cubed and they don't match up. But you can't set 8 sizes manually. No more walking out half spools

works great.

Lost the copper pice that is used to calibrate and have not been able to use. It seemed a good value tool.It would be good if the part hard a bag or something so as not get lost or I never had it?

Did not work so I ship the back haven’t got my refund
