These gauges perfectly fine and just what I expected.

Being able to read it. ,Not sure yet on accuracy. I'm trying to measure a both.Sometimes these are sent out to quickly.

A brief description of the meaning of the lettering inscribed on it would be helpful. Aside from that, great product, accurate, fasts shipping

I only got half of the shipment and had to wait an extended time for that piece to arrive. However, both my manager and district manager were both impressed with the once pice I did receive.
