It is designed for precise depth measurement of slots, holes, and stepped surfaces in machining, tooling, and metrology applications. The thimble uses a ratchet stop mechanism to apply consistent measuring pressure, contributing to its stated accuracy of 0.0002 inches. The 2.5-inch base length provides a stable reference surface. Each unit ships calibrated and includes a short-form certificate of calibration traceable to NIST standards. This instrument is intended for use by machinists, tool-and-die makers, quality control technicians, and precision measurement professionals.\u003c\/p\u003e\n\u003cp\u003eThis depth micrometer is suited for production floor and inspection room environments where precise linear depth measurement is required. The 6-rod set allows the instrument to cover the full 6-inch range in 1-inch increments. With a graduation of 0.001 inches and an accuracy of 0.0002 inches, it is appropriate for applications demanding close-tolerance verification. The included torque wrench supports proper rod installation. The instrument arrives ready for use with its NIST-traceable calibration certificate, making it suitable for quality management systems that require documented traceability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch maximum measurement range with 6 rotating interchangeable rods\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble for consistent, repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003e0.001-inch graduation with 0.0002-inch stated accuracy\u003c\/li\u003e\n  \u003cli\u003e2.5-inch base length for stable contact on reference surfaces\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable calibration included; ships calibrated and ready for use\u003c\/li\u003e\n  \u003cli\u003eIncludes protective case, short-form certificate of calibration, and torque wrench\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose mechanical depth micrometer for use in machine shops, toolrooms, and quality inspection environments requiring NIST-traceable depth measurement up to 6 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eRod changes should be performed using the included torque wrench to ensure proper seating and measurement integrity. Zero the instrument against a flat reference surface each time a rod is changed. Store rods in the included case to prevent damage to measuring surfaces.
