Universal gear testers are devices used to check a wide range of parameters of gears and other precision-manufactured parts. These testers are usually equipped with multiple measurement functions that allow them to check a variety of features such as pitch, involute contour, flank shape, module, circular tooth accuracy and others. Universal gear testers are generally widely used in the manufacture of gears and other precision-manufactured parts, as well as in workshops and laboratories engaged in the maintenance and repair of gears and other parts. It is important to note that universal gear testers must be regularly maintained and calibrated to ensure that measurement results are reliable. In addition, operators should carefully read and understand the operating instructions to ensure that tests are performed correctly. Universal gear testers can also be equipped with advanced measurement and control systems that allow them to perform fast and accurate measurements. In addition, they can be equipped with a variety of accessories and tools that allow them to check a wide range of parts and applications.
