This surface roughness tester provides precision accurate readings and displays multiple surface roughness parameters of Ra, Rq(Rms), Rt, and Rz. Unit utilizes an easy-to-use interface allowing for changes of in/mm (µin/µm), cutoff length, sampling length, parameters, level of test (stylus position), digital filters, and more. Measurement results are displayed as large characters on the LCD screen for
easy recognition.
