The Newage® MT91 System is an automatic microhardness testing system that uses the Rockwell method for the hardness result. Hardness is measured based on the depth of penetration rather than using an optical system to determine hardness based on the impression diameter.
The main advantages of the MT91 Series are its very fast test cycle coupled with its incredible test accuracy. No traditional microhardness testers can come close to matching the MT91 in speed
or accuracy, since no manual interpretation of the impression is required. Complete traverses in as little as a couple minutes - improve productivity ten times compared to standard methods - using Rockwell-type depth measurement at micro load ranges
