We are in the market for a new Rockwell Hardness tester, Been looking at the Starrett & Mitutoyo Bench top models and even considering the Starrett Portable Ultrasonic. Requirements are... needs to have NIST certification, Digital display and come with calibration test blocks. Anyone have experience with the portable units? Like the Starrett 3822 or 3821? How do they compare to the bench top models as far as accuracy?
