Rieker designs and manufacturers mechanical inclinometers using precision glass tube and ball construction; die-cast aluminum or polycarbonate housings with engraved or silk screened markings and customer specified color warning zones. The fluid combined with large, clear number and degree markings make it easy to get quick, accurate readings under a wide variety of severe environmental and operating conditions.•Quick Visual of Angle for Level or Roll Over Early Warning Indication•Custom Color Warning Zones (specified by the customer) •1, 2, or 3 Zones Available (Green, Yellow, Red) •Bright Visual Danger Indication
