Checklist For Protractors
- Absolute precision is essential here.
- Just a few degrees of deviation will make your work look crooked. In the worst case, the fit is no longer given and you have to start all over again.
- Ideally, you should use a modern device with a digital display that allows you to read off the angle to one decimal place.
- The deviations should not be more than 0.1° to 0.3°. This tolerance limit should not be exceeded.
- Values of a deviation of 0.5° or more are a real minus.
- Always make sure that the measuring range is as high as possible. Depending on the model, the values of the measuring range are from 0° to 270°. Some devices only cover a range of 0° to 200°, others 0° to 360 °.
- The longer the legs are, the more possibilities the protractor offers you. On the other hand, short legs are practical because they take up less space.
- However, we recommend a device with longer legs. The length of the legs of the different models varies between 30 cm and 45 cm.
- There are protractors that are made of plastic or metal. Many craftsmen prefer the models made of aluminum. They are a little more robust than the products made of plastic. However, in the end, this is a matter of personal taste.
- A built-in spirit level saves you a lot of additional measuring work. With some spirit levels, the bubble is inserted vertically, with others horizontally.
- However, some protractors also offer both variants, which significantly increases the convenience.
- Many protractors have an illuminated display, which is easy to read. Very few models hold magnetically.
- Also a scale is unfortunately searched in vain for some digital protractors. Thus, they can only be used as a ruler to a very limited extent.
- On the other hand, other manufacturers offer not only the metric system in centimeters used in mainland Europe but also the imperial system in inches commonly used in Great Britain and the USA.
- The weight of the offered models varies from just about 85 g to 1,400 g.
