The Qualitest QualiSurf I Portable Roughness Tester is a pocket-sized economically priced instrument for measuring surface texture conforming to traceable standards. It can be used on the shop floor in any position, horizontal, vertical or anywhere in between. The large display of the Qualitest QualiSurf shows (4) roughness parameters Ra, Rz, Rq and Rt at the touch of a button, combined with the selectable cut-off length. External calibration of roughness values is possible by means of a special CAL button, which makes adjustment of this instrument very easy. A beep signal informs the user of each individual measurement status when ready. The easy to use QualiSurf Ⅰ operates on various surfaces, not only flat but also outer cylinder, outer cone, grooves, and recesses greater than 80 X 30mm.

Qualitest QualiSurf I is most suitable for inspection departments, quality control, on the shop floor during machining, assembly and on-site. TR100 determines roughness parameters Ra, Rz, Rq and Rt within a wide measuring range (See specifications below). The piezo-electric pick-up stylus with diamond tip assures a very reliable measurement within tolerances in conformance with ISO Class 3. Ra parameter is in conformance to ISO while Rz conforms to DIN standards.
