| PTC Portable Steel Hardness Tester 316
The Model 316 Portable Steel Hardness Tester is designed for the 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.
The unit consists of two major components: a calibrated indenter and a direct reading microscope. The hand-held impact indenter drives a 1/16 inch diameter tungsten carbide ball into the sample being tested. The resulting indentation diameter - which is a function of the hardness - is measured with the 60X microscope. The calibrated reticle on the microscope reads C Scale directly in the range of 20 HRC to 65 HRC with an accuracy of +/- 1.5 points. The illunination system features a MagLite flashlight with a fiber optic pipe that directs the light to the focus of the microscope. The instrument is fully portable and easy to use. Flat or curved surfaces of virtually any configuration may be measured. The instrument's portability makes it particularly useful where the test piece is too large or too heavy to test on a bench type tester.
Model 316 includes a hand held impact indenter assembly, an illuminated, fixed focus, 60X magnification measuring microscope; a marked and calibrated hardness test block; test instructions; a convenient hardness conversion chart; and a carrying case. |
