230RL

The Starrett 230RL Precision Micrometer is an essential measuring tool for any workshop or laboratory that demands the highest level of accuracy. This micrometer, crafted by Starrett, a leading manufacturer of precision measuring instruments since 1880, is a testament to the company's commitment to delivering top-notch metrology solutions.

The Starrett 230RL features a rugged, anodized aluminum body with a 1-inch (25.4mm) diameter anodized aluminum thumb nut. The anodizing process not only enhances the appearance but also provides additional protection against corrosion and wear. The micrometer's spindle is made of hardened and precision ground steel for superior accuracy and durability.

The micrometer's precision-ground, stainless steel anvil-type thimble and 0.1mm (0.0004 inches) pitch thread provide exceptional resolution. The anvil-type thimble design ensures consistent contact between the anvil and the workpiece, while the fine thread allows for precise, incremental adjustments.

The Starrett 230RL comes with an accurate, clear, and easy-to-read 0.1mm (0.0004 inches) graduation scale. The scale is calibrated to ASME and DIN standards, ensuring compatibility with a wide range of industries and applications. The micrometer's vernier scale features a fine 0.01mm (0.00004 inches) graduation, allowing for even more precise measurements.

The micrometer's locking mechanism is designed for secure and reliable holding of measurements. Its positive locking feature ensures that the measurement remains constant, even during transportation or handling. The micrometer also comes with a protective carrying case to ensure its safety during transport and storage.

In summary, the Starrett 230RL Precision Micrometer is a high-precision, durable, and versatile measuring instrument. Its rugged design, fine graduation, and reliable locking mechanism make it an indispensable tool for metrology applications where precision and accuracy are paramount.
