Features
● Pocket-sized economically priced, completely portable instrument which performs traceable surface roughness measurements on a wide
variety of surfaces; can be used confidently in production on the shop floor and in the laboratory.
● Solidly built, with a durable cast aluminum housing, to provide years of accurate, reliable surface
finish gauging,
● Can be used to measure any one of four, switch-select-able, parameters: Ra, Rmax/Ry, Rz.
● Selectable traverse length 1, 3 or 5 cut-offs of 0.8mm/.030".
● Operates in any position - horizontal, vertical, and upside down.
● Four switchable probe positions - axial (folded) or at 90°, 180° or 270°.
● Even difficult-to-reach surfaces such as inside and outside diameters are accessible.
● Integrated data output for SPC-processing units that is compatible with the most common data
processing systems.
● Easy-to-read LCD readout presents the measured roughness value, in micro inches or micrometers,
within half a second after the surface is traversed.
● Out-of-range (high or low) and "battery low" signals are also displayed.
