Lightweight at just 275 g, this micrometer is easy to handle without compromising durability. Whether for inspecting machined parts, validating prototype dimensions, or conducting routine quality checks, this tool provides unmatched precision and efficiency in both inch and metric systems.
The Mitutoyo 293-831-30 Digital Micrometer (Inch/Metric) is a cost-effective precision measuring tool designed for professionals who demand reliability and accuracy. With a measuring range of 0–1″ (0–25 mm) and resolution of 0.00005″/0.001 mm, it delivers dependable results for a wide range of industrial and laboratory applications. Its highly stable frame with integrated heat shield reduces the impact of operator body heat, ensuring consistent accuracy over extended sessions. A ratchet stop mechanism guarantees repeatable measurements, while the clear LCD display enhances readability in busy work environments.
The Mitutoyo 293-831-30 is built for professionals who demand uncompromising precision and reliability. Its ±0.0001″ accuracy, carbide-tipped measuring faces, and heat-shielded frame make it a trusted choice for industries where every micron counts. With intuitive digital readout and inch/metric versatility, it blends Japanese craftsmanship with modern usability, ensuring consistent results across all measurement tasks.
Traditional micrometers often suffer from operator error, poor readability, or long-term wear that compromises accuracy. The 293-831-30 solves these challenges with a ratchet stop for repeatable measurements, an LCD display for instant clarity, and hardened components that maintain calibration over years of use. It eliminates guesswork, speeds up inspections, and ensures reliable compliance with strict tolerances.
In industries such as aerospace and automotive, even the smallest deviation can cause failure in assembly. The Mitutoyo 293-831-30 provides ±0.0001″ accuracy, ensuring precision when measuring shafts, gears, and other machined components. Its ratchet stop and stable frame with heat shielding help reduce operator error and maintain reliability during long production runs.
Manufacturers rely on consistent inspection tools to validate dimensions of finished parts. The digital display of this micrometer offers clear readings down to 0.001 mm, minimizing interpretation errors common with analog devices. In quality assurance labs, the tool helps verify tolerances for flatness, parallelism, and surface finishes with unmatched repeatability.
R&D environments require versatile measuring solutions for prototype validation. With inch/metric conversion, this micrometer supports engineers working on international projects. Its carbide-tipped faces and micro-lap finish deliver stable, long-term measurement accuracy, making it ideal for testing new alloys, composites, or precision-engineered components.
Maintenance teams benefit from portable and durable tools for equipment servicing. The 293-831-30’s auto power-off, low-battery alarm, and robust 275 g body make it practical for field use. Its repeatable accuracy ensures technicians can quickly confirm whether components meet wear and tolerance limits, reducing downtime and improving operational reliability.
