The model 16 Ames Portable hardness tester is designed to allow you to test the hardness of materials up to 16 inches in diameter. This tester has been referred to as a model 36 in the past because the chain is 36 inches long. This name caused confusion so the tester has since been renamed the model 16.
Model 16’s chain clamp system and dual “V” anvils allow testing round items from zero to16 inches in diameter. For testing Rockwell A, B, C and other scales. This tester can be ordered in standard or superficial versions. The measuring head is independent of the clamp and may be removed for mounting on a holder of your own design. This tester weighs 8 pounds and conforms to ASTM standard E-110.
