Cross-test vial enables simultaneous leveling in two directions.
8" precision machinists' spirit level with a main vial and a cross-test vial for determining horizontal plane.
Graduated, ground glass main vial has a sensitivity of 0.42 mm/m or 80 to 90 seconds and is adjustable to a positive setting for accurate results.

USED FOR: A level is a measuring tool with a liquid-filled vial with a bubble that moves when adjustments are made When it settles, it indicates that a surface is horizontally or vertically straight.
ACCURATE READINGS: This precision level has a graduation of 0.42 mm/m or 80-90 seconds, and the ground glass main vial is graduated and adjustable to a positive setting for accurate results.
TWO DIRECTION LEVELING: The second cross-test vial enables simultaneous leveling in two directions for precise measurements.
LEVELS ROUND ITEMS: An involute groove runs the entire length of the level base and provides a reliable seat for round work, such as leveling pipes or shafting.
Cross test vial allows simultaneous leveling in both directions.
Made from high-quality seasoned cast iron.
