The SPAN 3.5" Face Stem Mount Liquid Filled Subsea Gauge is a rugged and reliable pressure gauge designed for subsea, ROV, military, and marine applications. Featuring a 3.5" face, this gauge uses a liquid-filled design to minimize pointer movement, ensuring stable, accurate readings and longer durability in high-shock and vibration environments. The stem mount means the gauge is securely attached to a threaded stem, providing a straightforward and stable installation method, especially for applications where space or mounting options are limited. The gauge's Zytel case and ring offer exceptional resistance to chemicals, weather, and corrosion, while the patented internal compensating diaphragm (ICD) compensates for changes in temperature and external pressure, making it essential for deep-water use. Standard features include a white-on-black dial, stainless steel internals, and options like freeze-proof KEM-X Socket Savers, with the ability to be serialized and certified to NIST accuracy standards. This versatile gauge is perfect for demanding applications requiring reliable, long-lasting performance. 

All OneHydraulics SPAN Subsea Gauges come with NIST Calibration Certification.
