Rieker Inc. manufacturers Military Grade inclinometers using precision tube and ball construction. The 2126 inclinometer has a scale of ±26 degrees (º), in 2 degree increments, for a quick visual reference when measuring tilt. The tube is filled with a special damping fluid that controls the movement of the ball and will operate in wide MIL SPEC temperatures. Our industry leading ISO certified quality and control standards provides for the smoothest and most consistent roll among any inclinometer of this type worldwide. The housing is made of a rugged Military Grade 100% Polycarbonate, making these inclinometers extremely rugged and shatter-proof for all types of environments and weather conditions. The large, clear number and degree markings make it easy to get quick, accurate readings - clearly visible from 8- to 10-feet away. In ranges of ±5, 10, 26 and 45º there is a Rieker Inclinometer to fit most every application. Available in black or white.
