Product Details

“A step ahead!”- with MarSurf M 300 C

Cylindrical drive unit with hand prism and pick-up from
the PHT series!

Even more comfort and performance at a good price. An
investment that pays!

  • Easy hnadling through operator prompting
  • Brilliant, illuminated color display
  • Measuring range of up to 350 µm (.014 in)
  • Automatic selection of filter and traversing length
    conforming to standards
  • Integrated memory for the results of up top
  • 40,000 measurements and 30 profiles
  • 15 languages

The evaulation unit essentially corresponds to the model of the M
The main difference of the measuring station is the design and
the possibility to connect the RD 18 C.

The unit is connected by cable to the evaluation unit and has the
proven cylindrical size as its predecessor does.

Generally, the cylindrical drive unit is integrated in a hand
prism, but can also be used without the hand prism, for example
in plugs or devices.
