PTC Portable Steel Hardness Tester  52-342-3

Steel Hardness Tester: 316 Portable C Scale
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 is exceptionally useful where the test piece is too large or heavy to test on a bench-type tester. This high quality, affordable, portable tester is a must for large work pieces, small machine shops, heat treaters, quality control personnel, and engineers.

The slim design of the microscope allows the user to test in tight spaces which are not accessible to bench testers. 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.

• Range 20HRC to 65HRC (equivalent Rockwell C Scale)
• Accuracy ±1.5 points . Weight 2 lbs. 2 oz. (1 kg)
• Shipping Weight 4 lbs (1.8 kg)
• Test Block, and Carrying Case Included 

Equivalent to Rockwell C Scale

• A hand-held impact indenter drives a 1⁄16" diameter carbide ball

into the sample with a calibrated impact. The impression diameter

is read directly with a microscope containing a calibrated reticle.
