Our indicators are already in use by DOTs (highway departments), road districts, parks & recreation departments, landfills, military, municipal & county governments and USDA forestry. All tube-type indicators use a precision boro-silicate glass tube filled with a special dampening liquid that will operate in temperatures from -40º F to +180º F. The glass tube is tucked into the body for protection and to prevent dust and dirt build-up that could obscure visibility of the tube. The tube background is a bright yellow for easy viewing of the indicator ball. The indicator bodies are made of a rugged ABS compound and flat black to prevent glare. A series of ribs is built into each body to make them crush-proof. The bracket mounting system allows for adhesive strip mounting, or bolt mounting using (2) #10-32 screws (included). The bracket allows you to mount your inclinometer on the hood or dash, hang from the roof or any other surface that has a 1" by 2" mounting space.
