Mitutoyo Portable Rebound Hardness Tester HH-V400

The HH-V400 portable rebound-type hardness tester is designed to test the hardness of metals. Users load the impact hammer and hit a button that ejects a steel ball at the work-piece surface. The hardness tester measures the rebound velocity of the steel ball after it hits the test material surface, thereby calculating a HL hardness value. This value can be converted to other hardness scales as required.  

• Detector: Detector D is a standard type measuring Ø28 x 174.5 mm with a tip diameter of Ø22 mm. Has impact hammer and carbide ball at tip. Other detector types are available for purchase separately.
