These units have been discontinued however many of the units are still in service we still service,  repair, and calibrate the units. The parts that are not avalible we may have reconditioned.

Mahr PS1

With increasing manufacturing and machine quality, the surface finish technical products' is becoming ever more important than ever.

This makes it all the more crucial to offer metrological solutions with instrument designs that provide quick and simple yet standards-compliant measuring options.

In some cases measurements are transferred from the inspection room to production to save time and money. Components may be too large or heavy to be transported, leaving no alternative but to carry out measurements directly on the component or machine.

The Pocket Surf PS1 lives up to its claim of "Absolute mobility" in all manner of ways, providing:


Battery powered freedom

    Over 500 measurements without having to recharge the instrument.

An all-in-one solution that is no larger than a digital camera.

    Small and lightweight (400g / 0.88 lbs.).

Instrument flexibility 

    The standard range of functions is sufficient for this all-purpose smart little instrument to perform your

      measuring tasks.

All the measuring positions you need 

    Can be used horizontally, vertically, upside down or in any other position required by the component.

24 parameters 

    Offer the same range of functions as a laboratory instrument.

Error-free operation  thanks to an integrated roughness standard.

Automatic cutoff selection  (Patented) so that even non-specialists are ensured correct measuring results.

Simple operation

The pocket surf shows how simple the PS1 is to use. You quickly get to grips with the essential features, enabling you to complete your measuring tasks with excellent results


Large display


All the information you need at a glance.

All functions displayed in plain text.

Functions called up using arrow keys.

Defaults/language simple to select and change.



PS1 digital screen

Height adjustment accessory included in the scope of delivery. For many additional measuring tasks.                            Simply clips onto the bottom of the PS1.




height stand

Integrated calibration standard.

No external calibration standard required (patent pending). Gives greater reliability for standards compliant measurements.

Drive unit

Can be rotated and moved longitudinally. Enables the pick-up to be moved into the calibrating position. The pick-up is also protected for transport in this position.


PS1 nosepiece

Pick-up with removable pick-up protection      Standards-compliant measurement. 5µm (200 µin) diamond stylus tip. Measuring force 0.7 mN.

Directly selectable parameters

Ra, Rz


Freely programmable  F1 button for direct access to one of 24 parameters of your choice.

USB interface -  PS1 is detected without a driver

(Such as a memory stick).


Evaluation possible using MarSurf  XR 20 evaluation software or MarSurf XR 20 instrument.


MarConnect interface (RS232),


usb and data connections

Flexibility thanks to 4 internally threaded bores 


There are four tapped studs on the bottom of the PS1 for attaching your own special accessories.








mounting holes



Start button on right and left


Not only easy to operate whether you are left or righ handed but also practical if the instrument is used as a mini-measuring station for upside down measurements.

Pocket Surf PS1.

     Wide Range of Applications

The Pocket Surf PS1 comes with a simple mount for height adjustment.

This enables measurements to be performed on items such as cones.


height stand

Perfect upside down measurements are possible with the Pocket Surf PS1.

All you have to do is position the part and start measurement.

This means that small components can be measured without additional mounts.

Measurements on measuring stands.

The Pocket Surf PS1 can be easily be mounted on ST-D/ST-F or ST-G measuring stands.

The Pocket Surf PS1 is the perfect entry-level measuring instrument for a very wide range of standards-compliant roughness measurement.

One possibility offered by an optional end face vee-block is to measure surfaces perpendicular to the contact face.
