Mahr Federal Introduces Economical MarSurf® M 400 Skidless Surface Gage

-- Affordable skidless surface system features proprietary motorized probe height adjustment for quick auto-zeroing

-- Plus breakaway probe mounting for probe protection and faster probe arm changes

PROVIDENCE, RI - Mahr Federal has announced the addition of an economical and powerful new skidless surface evaluation system to its MarSurf® line of mobile surface metrology systems. The new MarSurf M 400 features proprietary motorized probe height adjustment which quickly and automatically zeros the probe in seconds and can cut measurement time in half. The M 400 also features a magnetic, breakaway probe mounting system which protects sensitive probes from accidental damage and facilitates fast probe changes. The MarSurf M 400 measures all common international parameters, and features Bluetooth connectivity between the measuring system and the evaluation unit with integrated thermal printer.

"Skidless tracing of surface characteristics is being more frequently required in production environments as it allows the capture of primary, waviness, and roughness profiles for the evaluation of the more complex parameters being required by today's products" said Pat Nugent, Vice President of Metrology Systems for Mahr Federal. "Our new MarSurf M 400 has been eagerly awaited as it offers this capability in a very economical, entry level system, and is the only one to include our proprietary auto-probe zeroing, which can dramatically increase the ease and speed of measurement. Our magnetic probe mounting system also protects delicate probes and allows probe arms to be rapidly changed with just a touch."

Operation of the M 400 is fast and easy. The measuring unit can be used alone in different orientations, in combination with various accessories, or mounted on a measuring stand. A large color display on the evaluation unit provides clear, concise results and intuitive operator guidance. The unit is compatible with all appropriate DIN, ISO, JIS, ASME and MOTIF standards for the measure of most common surface finish parameters from the P, W, and R profiles.

The MarSurf M 400 comes in its own carrying case and includes the M 400 Evaluation Unit with integrated thermal printer, and Bluetooth connectivity with the newly designed SD 26 Drive Unit with the breakaway BFW 250 probe system and standard probe arm. Battery or AC adapter operation extends flexibility, and two USB cables allow connection to a PC or optional use with the drive unit.
