Key benefits 0.01 mm precision: lever gauge indicates accurate measurements with a base that securely clings to metal surfaces for stable operation. Stable performance in demanding environments: suitable for metalworking shops, mold manufacturing facilities, and equipment maintenance scenarios where submillimeter accuracy matters. Essential for professionals: ideal for machinists, inspectors, and automotive technicians requiring repeatable dimensional verification in workshop or production line environments. Durable and versatile construction: engineered with a large diameter rotating gauge, anti rust aluminum alloy construction, and an adjustable base that rotates for visibility and flexible positioning in tight spaces. Practical use scenarios Metalworking setup and inspection: verify critical dimensions during milling or turning operations to ensure parts stay within tolerance. Mold manufacturing and component checks: assess cavity alignment and component fits to support precise mold production. Online maintenance and QA: perform repeatable dimensional verification on fixtures and assemblies in workshop or production line environments.
