SURFACE FLATNESS TESTING INSTRUMENT
Product Detailed

convenient to carry
With bright cross-line in dark field of view,a clear image and easy reading
capable of measuring the strai

Features

With the line division value,it is intuitive and easy to calculate the error of straightness and flatness. This instrument is simple in design,therefore it is convenient to carry,and can be used in various condition. With bright cross-line in dark field of view,a clear image and easy reading are obtainable. Combining with optical square which uses pentaprism and reflecting mirror with magnetic holder,the instrument can measure the error of strainghtness and squareness between guideways which are vertical to each other. It can easily catch the reflecting,image from far distance by using optical viewfinder combined with the level adjusting plate. It is capable of measuring the straightness separately in both vertical and horizontal directions by rotating the eye piece 90°.
