Starrett 310 mm I-Beam Spirit Level Cast Iron Frame with Adjustable Main Vial 98AZ-12

The Starrett 98AZ-12 310 mm I-Beam Spirit Level features a robust cast iron frame that provides high durability and precise measurement for industrial and workshop use. Engineered with a unique involute 'V' groove between the bearing flats, it ensures accurate seating on round surfaces like pipes and rods. This model is particularly equipped with an adjustable main vial marked with graduations spaced 2.5 mm apart, conforming to BS3509 sensitivity standards.

In addition to the main vial, this 310 mm version includes a plumb vial for vertical alignment applications, enhancing its versatility in leveling tasks. The main vial is constructed with ground glass to offer exceptional visibility and measurement accuracy. The waterproof and milled surface design protects the spirit level against harsh environments, making it suitable for mechanical workshops, industrial measuring, construction, and maintenance tasks.

This spirit level is non-magnetic, preventing interference with sensitive equipment and materials. Its height and width of 58 mm and 36 mm respectively make it compact yet effective for precise leveling. The bubble movement calibration means a 2.5 mm displacement correlates to a tilt of 0.12 mm across 300 mm, ensuring fine adjustments can be easily detected.
