0.01 mm accuracy provides precise, repeatable measurements for quality control in workshop or production environments. Base securely attaches to metal surfaces to prevent movement during measurement, supporting stable readings. Large diameter rotating gauge offers clear visibility and reduces parallax errors when reading measurements. Antirust aluminum alloy construction delivers durable performance in demanding workshop conditions. Adjustable base rotates to optimize visibility and positioning, enabling flexible use in tight or awkward spaces. Bidirectional scale markings allow you to read measurements from multiple angles without repositioning the instrument. Shockresistant mechanics enhance reliability for daily industrial use. Designed for machinists, inspectors, and automotive technicians who require repeatable dimensional verification in workshop or production line settings. Applications: Verifying workpiece dimensions and setup tolerances on a milling or turning operation. Conducting quick, repeatable checks of produced parts on a production line for quality control. Assisting in automotive assembly or tasks where precise alignment and measurement verification are needed.
