CV Instruments has launched the CV R-190 Universal, Bench Surface-Roughness Tester, equally at home in a company’s production environment or within a technically demanding laboratory.
Based on an advanced skidless measuring system, the R-190 uses an inductive pickup with interchangeable styli, and is able to measure in a wide range of roughness parameters, including – Ra, Rz, Rt, Rp, Rv, Rq, RSm, RmaxD and material ratio curve, with additional roughness parameters available on request. Aiding the advanced unit’s flexibility, the large capacity, 0.001 um resolution tester has ‘cut-off’ option lengths of 0.08 mm, 0.25 mm, 0.8 mm and 2.5 mm.
With a main 500 mm work column, based on a solid granite base, the R-190’s adjustable tracer is able to operate a minimum distance of 100 mm or a maximum of 380 mm from the unit’s granite surface. The tester’s worktable has a 360-degree rotational range and is able to incline through +/- 10-degrees, the unit also has a range of ‘V’ blocks that are able to accommodate a variety of sizes of cylindrical components.
The R-190 is supplied with two styli, a standard stylus, intended for roughness tests on plain and round surfaces, and for use within bores from 10 mm diameter, with a maximum depth of 18 mm. A second stylus is included for use on plain surfaces, and in bores from 4 mm diameter, with a maximum depth of 15 mm. A high quality PC, including Windows XP, and easy to use control and drive units are included in the comprehensive CV package.
