Is your Ames Hardness tester genuine?

How to tell if your Tester is a Genuine Ames Hardness Tester

Ames began making Ames Portable Rockwell Hardness Testers in 1947.  In 1975 Ames was acquired by Electro Arc.  The Ames line of portable hardness testers has been made in Michigan since.

In 1997 it came to the attention of the Electro Arc company that each of it’s testers had been purchased by a company in China and duplicated.  Now Chinese copies of Ames Portable Hardness testers are available online, bearing a striking resembelance to the handcrafted testers we manufacture everyday.  Each of our testers are built one at a time following the ASTM E110 standard for the Rockwell scale.  Each genuine Ames Hardness tester is individually calibrated to the Rockwell scales and bears a signed certificate with each tester.

How important is metal hardness testing? Consider the information provided by hardness testing and its significance in structural (i.e. bridges), aerospace, automotive, quality control, failure analysis and many other forms of manufacturing and industry. Determining material properties provides valuable insight to the durability, strength, flexibility and capabilities of a variety of component types from raw materials to finished goods.
