Spi 30-412-1 Dial Caliper 0-6 Inch 0.001 Graduation

Product Description

The SPI 30-412-1 is a dial caliper designed for precise linear measurement in shop, field, and service environments. It covers a range of 0 to 6 inches with a graduation of 0.001 inches per division and a beam graduation of 0.1 inches per revolution, allowing technicians to take fast, accurate inside, outside, depth, and step measurements. The caliper body is constructed from Super Polymid, a durable engineering polymer that resists corrosion and reduces weight compared to steel alternatives. A shockproof measuring mechanism protects the dial from impact damage during regular shop use. The white dial face improves contrast and readability in low-light conditions. Net weight is 0.3 pounds.

This dial caliper is suited for use in HVAC, plumbing, electrical, and general mechanical trades where component dimensions, pipe OD, fitting clearances, or part tolerances need to be verified quickly. It is a practical bench or bag tool for technicians performing field measurements or equipment installation checks. The thumb wheel jaw adjustment allows controlled, single-hand positioning for repetitive measurements. With a 1.57-inch jaw length, it accommodates a wide range of workpiece profiles without repositioning.

Installation Notes

No installation is required for this measuring tool. Before use, verify the jaws close fully to a zero reading and adjust the dial bezel if needed to null the indicator. Keep the measuring faces clean and free of debris to ensure accurate readings. Store in a protective case when not in use to prevent impact damage to the dial mechanism.
