The Martest 800 feeler gauge from Mahr is a high-precision measuring instrument specifically designed for use in workshop conditions. With a reading accuracy of ±0.25 mm and a resolution of 0.01 mm, it provides reliable results when testing for deviations from nominal dimensions. The device features a robust, matte chrome-plated protective housing that offers corrosion resistance and prevents the ingress of liquids. The rotating dial and the swiveling, replaceable measuring probe with a carbide ball allow for flexible handling and precise measurements. The shock-resistant design and the use of jewel-bearing measuring mechanisms ensure durability and accuracy. The feeler gauge is ideal for run-out tests, internal measurements, as well as for checking the parallelism and flatness of workpieces.
