Paste changes color when it’s submerged to indicate the gasoline level in a tank.

Built to resist corrosion and last in harsh environments, these vertical rulers are iron with a porcelain-enamel finish. Mount them to walls and tanks.

Connect continuous segments to create a ruler up to 10 ft. long.

Also known as oil-gauging tapes, use these tape measures to check the level of oil and other fluids in deep, large containers such as tanks and vats.

Permanently mount these rulers on machines, tanks, and walls to measure heights and depths.

Measurements are printed from top to bottom for measuring heights and depths.
