The APEX 590GN is a brass plumb bob designed for SAE oil gauging applications. The cylindrical body reads up, making it well suited for measuring fluid levels in storage tanks and similar vessels. Measuring range spans 0 to 6 inches, overall length is 7.3 inches, and the unit weighs 1.4 pounds. The solid brass construction resists corrosion and provides the density needed for accurate, stable readings. This tool is used by service technicians, pipefitters, and plumbers who require a reliable reference point when gauging liquid levels or establishing true vertical in the field.
The 590GN fits residential and commercial service scenarios where SAE oil gauging is required. Its cylindrical shape and upward-reading graduation make it practical for tank gauging, pipeline work, and general layout tasks that demand a consistent vertical reference. The 1-inch width and compact overall dimensions allow it to seat cleanly in standard gauging ports and fittings without obstruction.
Designed for SAE oil gauging applications in residential and commercial service environments where a cylindrical brass plumb bob with upward-reading graduations is required.
Installation and use of this plumb bob should be performed by a qualified technician familiar with tank gauging procedures. Ensure the tank or vessel is properly depressurized and safe to access before lowering the bob into a gauging port. Keep the bob and line free of kinks or obstructions that could affect accuracy. Follow applicable industry and site safety guidelines when working around fuel storage or pressurized systems.
