Duromètre portatif pour l’acier
- PTC Instruments - 316
PTC®'s Model 316 Portable Steel Hardness Tester measures the hardness of metals in the range of 20 to 65 HRC on the equivalent Rockwell C Scale. The instrument is fully portable and easy to use . It can easily be carried anywhere an accurate hardness test is required. This high quality, affordable, portable tester is a must for large work pieces, small machine shops, heat treaters, quality control personnel, and engineers.
PTC®'s Model 316's illumination system has been completely redesigned for optimal performance. The new light source is an aircraft grade aluminum flashlight with a fiber optic light pipe. The new slim design of the microscope light which allows the user to test in tight spaces which are accessible to bench testers.
The unit consist of two major components. A calibrated indenter and a direct reading microscope. The hand held automatic indenter is used to make a small indentation in the piece to be tested. The microscope is the used to directly 'read' the hardness from the size of the impression on its equivalent Rockwell C Scale. The Model 316 is used by heat treaters, engineers, quality control inspector and shop personnel to test the hardness of metals in such industrial equipment as dies and punches, gears, cutting teeth, welds, hardened way, bars, rods, nuts, bolts, rivets, etc...
PTC®'s Model 316 Steel hardness Tester comes complete with a calibrated impact indenter, illuminated microscope, calibrated test block, conversion calculator, and carrying case. The hand held indenter features a 1/16 inch diameter tungsten carbide ball tip. This makes a small spherical indentation the material being tested. The 60 X microscope features a direct reading reticle. The illumination system features a Maglite® flashlight. The fiber optic light pipe direct the light to the focus of the microscope. The calibrated test block can be furnished with certification to ASTM E18
