These hardness testers offer high accuracy, wide measuring range, simple operation, and compact size. Both units measure by calculating the ratio of the impact velocity of a mass to the rebound velocity. Perform tests and automatically calculate the mean value and convert to Vicker, Brinell, Rockwell, and Shore values.
Model 59977-20 with separate probe features easy to follow, menu-driven operation, backlit LCD, and RS-232 interface. Includes impact device D, calibrated test block, carrying case, and cleaning brush.
Model 59977-24 with integral probe is extremely versatile; take it anywhere and perform tests on any metal, at any angle-even upside down. Store up to 2000 readings and download using the RS-232 output. Includes impact device D, test block, and carrying case.
