Sounding Rods — IMPA 370306-370309

Sounding rods are essential for measuring liquid depths in fuel, ballast, and fresh water tanks on board cargo ships, container vessels, tankers, and offshore support vessels. Chief engineers and deck officers rely on these graduated rods to verify tank contents, detect water ingress, and maintain accurate stability calculations. On tankers, they are critical for monitoring cargo and slop tanks; on container ships, they help manage ballast operations. Without a reliable sounding rod, routine tank gauging becomes guesswork, risking overflow, contamination, or stability issues.

Each rod is machined from solid brass for corrosion resistance in salt-laden marine environments. They are available in straight or folding configurations, with a choice of square or round profiles, and feature a lifting ring at one end for secure handling. Graduations can be supplied in metric or imperial units to match your vessel's requirements. The full series covers IMPA codes 370306 through 370309, with four variants in total. Every code is ordered and priced individually, so you can specify the exact folding sections, shape, length, and graduation system needed for your application.
