The Keson LSB24D Sola Digital Box Beam Level is a 24-inch electronic inclinometer constructed from an extra-strong aluminum profile with reinforcing ribs for enhanced stability. It features three patented Sola Focus Vials, which provide 60% magnification and improved contrast for clear readings from various angles and lighting conditions. The integrated electronic inclinometer module offers digital readouts in degrees, percent, mm/m, or in/ft, with an accuracy of 0.05° at 0° and 90° and 0.1° between 1° and 89°. This level includes an adjustable inclination display, a hold function for storing measurements, a reversible display for inverted measurements, and switchable audible signal guidance. Vial accuracy is ≤ 0.3 mm/m (0.017°) in the standard position and ≤ 0.5 mm/m (0.029°) in inverted measurements. It is equipped with shock-absorbing 2-component end caps for protection and carries an IP65 protection class rating, making it dust-tight and resistant to water jets. Bluetooth connectivity allows iith the free Sola Measures app for remote readings and data management.
