Steel Hardness Tester

• Designed for accurate, rapid in place measurement of the hardness of steel and steel alloys in the range from 20 to 65 on the equivalent Rockwell C Scale
• Unit consists of two major components: calibrated indenter and direct reading microscope
• Hand-held impact indenter drives a 1/16" diameter tungsten carbide ball into the sample being tested
• Resulting indentation diameter is measured with 60X microscope
• Calibrated reticle in the microscope reads C Scale directly with an accuracy of ±1.5 points
• Illumination system features a MagLite® flashlight with a fiber optic pipe that directs the light to the focus of the microscope
• Particularly useful where the test piece is too large or too heavy to test on bench-type tester
