The Sokkia B40 (and its updated B40A model) is a highly precise, rugged automatic optical level widely used in construction, civil engineering, and surveying. It is designed to establish or check horizontal planes, height differences, and distance measurements with exceptional reliability.
Magnification: 24x optical zoom for clear, sharp viewing.Accuracy: Standard deviation of ±2.0 mm for a 1km double-run leveling.
Ultra-Short Focus: Can focus on objects as close as 20 cm (7.9 inches) from the end of the telescope, making it ideal for confined, tight spaces.
