The Martest 800 feeler gauge from Mahr is a high-precision measuring instrument designed for a variety of applications in manufacturing and quality assurance. With a robust, matte chrome-plated protective housing and a high-contrast dial, it offers both durability and clear readability. The integrated dovetail guides ensure stable clamping, while the shockproof measuring mechanism and the anti-magnetic design enhance the reliability of measurements. The device allows for automatic adjustment of the probing direction and is equipped with a ball-bearing double lever that is protected from overload by a slip clutch. The measuring tip with a 2 mm carbide ball ensures precise measurements, while the sealed display prevents the ingress of liquids, making it suitable for use in workshop conditions.
