Mahr 2191802 Pocket Surf IV 5µm Probe Surface Roughness Gage

The Mahr 2191802 Pocket Surf IV is a new, portable, battery-operated contact surface roughness profilometer designed for shop-floor and in-process surface finish inspection. It ships as a complete kit including the Pocket Surf IV gage unit with integrated 5 µm radius diamond stylus, a CalSurf certified roughness reference standard, Mahr calibration certificate, 9V battery, carrying stand, foam-lined hard-shell carrying case, and instruction manual (Doc. No. 2254734 Rev 2.0, 10/2018). The instrument measures multiple roughness parameters including Ra, Rz, Rmax, Rq, and Rt per ASME B46.1, ISO 4287, DIN, and MIL standards, with a measurement range of 0.05–100 µm Ra and resolution to 0.001 µm; it outputs SPC data via RS-232 serial port for integration with statistical process control systems. The unit is Made in USA (visible on case label, serial 2191802), CE marked for international compliance, and powered by a single 9V battery — making it fully self-contained for use anywhere on the production floor, quality lab, or in the field without AC power.
