Backlit Inclinometers:  Mechanical "Ball-in-Tube" Type


These highly visible backlit models were specifically developed for fire trucks that are required to have all instrumentation lighted models 1017 (10) and 1023 (20) comply with National Fire Protection Association 1901 Standards for Automotive Fire Apparatus.

However, these are well suited for any industry when instrumentation must be visible in low light or night operation. Available in single piece and OEM volumes alike.

Also referred to as a clinometer or ball in tube level, the "-12VT" models are backlit versions of our precision inclinometers that have been in the field for decades.

Same high quality expected from Rieker, with a new innovative technique that lights the tube (not the housing) so you can actually see the ball position. Available with customer specified color zones on the tube for best visibility.

Equipment Types

Aerial lift trucks, Bucket/utility trucks, Cranes, Construction Equipment, Conveyor and Material Handling Equipment, Emergency and Fire trucks, Government and Military Vehicles, Trailers.
