PTC Instruments 316 offre

The 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.

The slim design of the microscope allows the user to test in tight spaces which are not accessible to bench testers. The handheld automatic indenter is used to make a small indentation in the piece to be tested. The microscope is then used to directly "read" the hardness from the size of the impression on its equivalent Rockwell C Scale.

Certification of the microscope and/or calibrated test block using standards calibrated traceable to NIST are available upon request for nominal fees.

Caractéristiques

• Unit consists of two major components: a calibrated indenter and a direct reading microscope
• Hand-held impact indenter drives a 1/16" diameter tungsten carbide ball into the sample being tested
• Resulting indentation diameter - which is a function of the hardness - is measured with the 60X microscope
• Calibrated reticle in the microscope reads C Scale directly in the range of 20 HRC to 65 HRC with an accuracy of ±1.5 points
• MagLite® flashlight with a fiber optic pipe that directs the light to the focus of the microscope
• Flat or curved surfaces of virtually any configuration may be measured
• Particularly useful where the test piece is too large or too heavy to test on a bench-type tester
