MAHR M300 6910401
PRODUCTION-RELATED SURFACE ROUGHNESS MEASURING
MOBILE WITH MAHR M300
Wherever surface structures influence the function, processing or appearance of components or products, careful testing is essential. But how can surfaces be tested? At the start of the 20th Century, experts still had to test by eye and touch. A practiced eye can detect features in the µm range, and even the much maligned thumbnail test delivered perfectly acceptable results. Now however, we live in an age of exchangeable parts, fits and internationalization, where subjective tests like this are no longer adequate. Today, computer-aided measuring instruments provide objective data. Measurement and evaluation have become considerably easier. For decades, Mahr has been a worldwide pioneer in this area, as demonstrated by the company's numerous innovations and patented solutions in the field of roughness metrology. The interplay between the stylus, drive and measuring setup plays a key role in influencing the quality of surface measurement tasks. This is where Mahr's core expertise comes in, as demonstrated by the company's numerous innovation and patented solutions. Over time, we have succeeded in perfecting the stylus method which is now widespread throughout the world. The cable-free Bluetooth connection between evaluation unit and drive unit is unique in roughness metrology. Even here, Mahr shows that its metrology is up to date with modern needs.
MarSurf. Handy and precise for on-site roughness measurements
MOBILE ROUGHNESS MEASUREMENT DEVICE MARSURF M 300
Mahr has played a key role in ensuring the success of mobile roughness measurement devices. As early as the 1980's, Mahr was setting new standards with the M4P. The products have developed in line with changing production monitoring requirements. Today's devices meet the highest international standards. Mobile roughness measurement devices from Mahr are lightweight with a handy shape, flexible handling, high-precision measurement in different positions and easy positioning using V-blocks.
MarSurf M 300
High mobile, high-performance unit
Description
The operation of this instrument is based on the well-proven catalog of functions which enables instrument settings such as measuring conditions, language and record contents to be selected very easily, thus offering a maximum of comfort and flexibility.
The MarSurf M 300 not only meets the requirements for determination and documentation of selected parameters, but also makes most of the parameters and characteristic curves stipulated in DIN/ISO/JIS available for the evaluation of the profile assessed.
Moreover, the MarSurf M 300 offers an integrated memory for up to 40,000 results or 30 profiles, as well as the functions of tolerance monitoring, vertical scale selection and the setting of un-symmetric intersection lines for peal count calculation.

MarSurf M 300 Novelties
Up to 4 m distance between evaluation unit and drive unit enable high flexibility for you to conduct your measurements. Especially with large, cumberson parts, the application engineer can work directly at the measuring site. The measurement can be started at the evaluation unit MarSurf M 300 or at the drive unit Marsurf RD 18. The evaluation unit stand in a "safe place" and delivers exact results without influence from the ambient conditions
Brilliant, illuminated color display
A large, illuminated color display to read the parameters and the profiles so that you can:
read the correct results in a poorly lit atmosphere
Bluetooth Technology
NEW: cable-free connection between evaluation unit and drive unit
A further advantage of the Bluetooth technology:
Connection of several drive units to one evaluation unit. You can select your desired drive unit from a list.
Software "MarSurf PS1/M 300 Explorer" for mobile roughness devices
The essential functions of the Software "MarSurf PS1/M Explorer" are to secure and document your measuring results and profiles.
The data stored in the MarSurf M 300 can e.g. be printed out in any format.
The measuring data con be displayed in different forms:
● Profile and results
● Results
● Profile + MRK + results
● Statistics, and much more
The "Software "MarSurf PS1/M 300 Explorer" additionally simplifies the securing of data on your PC. During installation, a Mar Surf M 300 directory is automatically created. The results and profiles saved in the M 300 can simply be moved to that directory or any directly of your choice using "Drag & Drop" and are therefore secured.

Drive unit MarSurf RD 18
Description
The drive unit RD 18 can be connected to the MarSurf M 300 and is included in a carrying-case set. It can be connected either via Bluetooth or with a cable. The well=proven PHT-skid probes are implemented in the drive unit. To test the standard probe, a testing standard is already integrated in the RD 18 - this gives you the certainty that your results are correct.
To fasten individual accessory elements, 4 inside thread sockets are located on the underside of the RD 18. Furthermore, the prismatic underside offers you the possibility to perfectly position your work-pieces.
