Hardness Conversion Chart for Brinell, Rockwell, Vickers

Hardness Conversion Chart for Brinell, Rockwell, Vickers

 Easy to Use - No experience required; can be used in any position and in any space that will allow for the operator’s hand. The hardness reading is instantly indicated on the dial, which is divided into one hundred graduations. No waiting, preloading or separate measurements. Lightweight - The Impressor weighs only 1 lb. 2 oz. and comes complete with carrying case, adjusting wrench and two spare indenters.    For accurate readings, material should be at least 1/32" thick and large enough for a minimum distance of 1/8" in any direction from the indenter point to the edge of the specimen. The testing area should be smooth and free from mechanical damage. Simply exert a light pressure against the instrument to drive the spring-loaded indenter into the material. The indenter must be perpendicular to the surface being tested. On very soft metal, the highest reading should be used since cold flow permits the spring-loaded indenter to continue penetration.
