Tired of guessing whether a machined part meets the required finish? The Mahr MarSurf M 310 Portable Surface Roughness Tester 6910265 4.3" Touch LCD gives you instant, reliable roughness data wherever you work. It replaces costly lab visits and eliminates the risk of rejected parts, saving you time and money. You also avoid the hassle of sending samples to a lab and waiting days for a report.
Mahr MarSurf M 310 Portable Surface Roughness Tester 6910265 4.3" Touch LCD
The main problem many technicians face is the lack of a quick, accurate way to measure surface texture on site. Without that information, they cannot verify compliance with ISO or customer specifications, leading to re-work and lost confidence. The Mahr MarSurf M 310 solves this by combining a tactile stylus probe with a 4.3-inch touchscreen, delivering over 30 roughness parameters in seconds. Its portable design and built-in battery let you move from machine to machine, while USB and SD interfaces make data export painless. The device also stores thousands of profiles, so you can compare new measurements with historic data at a glance.
