At present, Sanfeng Measuring Instrument (roughness meter, roundness meter, contour meter, coordinate measuring machine, hardness tester, projector, imaging instrument, etc.), which has the highest market share in the domestic market, is a high-quality length measurement brand in the world. To choose a suitable model of Sanfeng measuring instrument for your own needs, you first need to determine the functional requirements of your measurement task, and then choose a measuring instrument that can meet these hardware requirements. Below is a brief introduction for everyone.

When determining the functional requirements of the Sanfeng measuring instrument, multiple factors should be considered, which can be referred to as follows:

The characteristics and type of the workpiece being tested: is it flat, circular, or of other types? Is it measuring the inner diameter or outer diameter? Is the location easy to access? Is it a protrusion, a hole, or a narrow groove next to him?

Accuracy: There should be a reasonable relationship (usually 5:1) between the workpiece tolerance and the resolution accuracy and repeatability of the measuring instrument, and the statistical GR&R test is usually 10:1. Are the precision of the measuring instrument you are using and the tolerance of the workpiece being measured appropriate?

Testing cost: As the accuracy of the measuring instrument improves, the cost will increase sharply. In order to approach the tolerance, you need to verify whether it is necessary to choose a costly measuring instrument before establishing the measurement operation.

Time and Capacity: Are fixed and specialized measuring instruments more flexible in operation and versatile in use? Of course, it depends on whether your production capacity is in bulk or multiple single pieces. You also need to consider which measuring product in the production cycle can truly save the measurer's time.
