The global spreading of the Corona virus COVID 19 leaves us facing challenges of an unexpected kind!


The well-being and safety of our employees at Status Pro GmbH (Ltd.) is of utmost priority. The result of our precautionary measures ensures continuity in delivering the highest standards of business and operational performance during these difficult times.


We are still 100% prepared and ready, either:

  • over the phone
  • through the Internet/vidcons etc.
  • on-site if necessary

Contact us!
+49 2327 9881 0

All departments are still contactable, under implementation of the new safety regulations (partly in shift work and partly as home-office).




We can still help you with training in spite of these difficult times.

  • In the Form of a Video-steam Conference or Demo:
    We can show you all our instruments and many applications including software through live streaming from our Training center.
  • In some cases we can also visit you at your premises:
    Sometimes there is no alternative performing test measurements on your machine.  Particularly if the is new for us or or the requirements are not typical.
    In such cases with some planning and with the correct protective equipment and procedures we can come to your facility.


Maybe this is a good opportunity to freshen up on training.

  • Per Video-conference:
    Either we do the measuring and stream to you or you do the measurement and stream the video to us. Just call us so that we can plan it.
  • Conventional training at your premises:
    With good planning we can still do conventional trading at your premises.
    We can insure that it is contact free and maintaining the appropriate distance.
    We have the necessary protective clothing.

Service work and surveying, on-site:

Utilise the time at hand to inspect and survey your machinery and ultimately bring it up to scratch for when the ball starts to roll again.
Our professional measurement and adjustment team are ready and prepared for an on-site visit. Observing the new safety regulations (distancing, hygiene, protective clothing etc.) , maintenance work can be carried out as safely as before.This could be an ideal time to have your machine geometry measured. Again with the appropriate planning and equipment we can still do the all the measurements as before. 

Please call us and we will see what we can arrange.

Straightness ApplicationStraighness Measurement of linear guides

Straightness Measurement


Traditionally with a wire and a spirit level, in fact the wire and the spirit level are two very different measurements, they measure different characteristics of a guide. Here the wire measurements are absolute measurements where the spirit level measurements are incremental. Additional we measure an angle with the spirit levels and calculate the hight. So there can be large differences between spirit level measurements and laser based or granite stone based measurements.

The advantage of our ProLine system is here that we measure both axis simultaneously and absolute!

Sketch of Straighness Measurements

Straightness according to the Norm DIN ISO 1101 is defined as follows: The tolerance zone is defined by two parallel lines drawn above and below the best fit of the measured data. The lines are separated by the tolerance (t). Naturally, a line is defined by the shortest distance between two points. If we have 20 points then the “best fit” line is the line through these points where the sum of the errors is a minimum. The tolerance lines are drawn parallel to this best fit line.

What does measuring straightness mean?

A line is a straight curve. We measure the "not straightness" or the curvature of something which looks straight from a distance. In engineering applications we measure and correct the straightness of machine components.

Typically we are dealing with a mixture of all of following deviations: Horizontal curvature, vertical curvature, Roll, Screw and Surface discontinuities. Depending on the measurement method chosen these deviations will be more or less visible and more or less separable. The chosen mechanical adaptation is often as important as the measurement technology. We are looking for practical methods and procedures for measuring, correcting and documenting the “not straightness” of long machine components like linear guides.

The best method for you depends on the following:

  • What exactly are we measuring? (Dimensions, accessibility, environment)
  • What is the required spec? (tilt, roll, line deviation, waviness etc )
  • What provisions (adjustment screws) are available to correct the deviations?
  • Who is doing the work and how much time does he/she have?
  • What kind of a report is required? (For whom?)
  • What’s your budget?
