The Mahr Pocket Surf IV Mobile Roughness Tester measures four selectable parameters: Ra, Rmax/Ry, and Rz, displaying a reading of all the parameters after the measurement is completed. The tester features sturdy housing made of cast aluminum, providing accurate and reliable measurement operation over many years. The measuring length is adjustable based on 1x, 3x, or 5x the cutoff wavelength of 0.030in (0.8mm). The tester can be implemented in any position – horizontal, vertical, or upside down. Four locking probe positions are available: axial, or 90°, 180°, or 270° angle. The tester applies MarConnect data output for simple data transmission, and is compatible with standard data recording systems. The easy-to-read LCD displays the measured roughness parameters in μm or μinch immediately after scanning the surface. Messages indicating when ranges exceed or fall below a limit and a battery warning symbol are also displayed. The tester is equipped with a long battery life via an easy to replace 9V battery.
