Preliminary Inspection of the Bevel Protractor Measuring tools and equipments to prepare for this bevel protractor calibration are: So, if you want to learn further, you can read the standard entirely. The process of calibrating protractors discussed below is based on the standard requirements of bevel protractors stated in the BS 1685:2008 standard, entitled “Bevel Protractors (Mechanical and Optical) – Requirements and Test Methods”. ![]() The analog version employs a vernier scale. This model is available in analog and digital version. It measures down to 5 minute resolution (the smallest reading). Bevel Protractor Calibrationīevel protractor or vernier protractor or micro protractor or universal bevel protractor is the most precision model of protractor. International standard such as ISO 9001 and ISO 17025 which covers general calibration requirements define personnel or lab who can conduct calibration. In this article, we are covering only the bevel vernier protractor and the double arm protractor models, because these two models are frequently used for a considerable accuracy.īut still, it is advisable that an accredited/certified calibration lab shall conduct that protractor calibration, like any measuring device. That said, the way to calibrate for each type is also different. There are different types of protractors (half-circle, single-arm, double-arm, vernier model, etc). ![]() This article will provide a basic idea of the techniques for calibrating protractors conducted by certified calibration laboratories as well as a simple guide and idea of protractor calibration beneficial for people who use their protractors for hobbies, interests, and small businesses and workshops.

What is the way to assess that your protractor’s accuracy is still within the permissible accuracy (tolerance)? What if your protractor actually needs a replacement? All of these questions can be answered with a protractor calibration.
