Mitutoyo Digital Thickness Gage with SPC output

This hand held digital thickness gage with ceramic anvils will accurately measure thicknesses of paper, film, sheets of metal, plastic, fabric, etc. as well as round or cylindrical objects in metal and wood working, biological and research situations. If you choose, the SPC output to printers or computers make data collection quick and simple.

These gages are not "water proof" and care must be taken to keep liquid sprays away from them. The anvils are flat, 10 mm diameter, top and bottom. They can not be exchanged or replaced. This particular gage has a somewhat larger measuring range than most other models.

As of 2014, these models have the letter "S" appended to them. You can avoid getting ripped off with a Chinese Mitutoyo imitiation by purchasing only from authorized Mitutoyo distributors. Be particularly careful when ordering "too good to be true" versions of these on eBay.
