The SPAN Liquid Filled 4.5" Subsea Gauge is a durable, high-performance pressure gauge designed for demanding subsea, ROV, military, and marine applications. Featuring a 4.5" face and liquid-filled design, this gauge reduces pointer movement, ensuring stable and accurate readings in high-shock and vibration environments. The Zytel case and ring offer excellent resistance to chemicals, weather, and corrosion, making it ideal for harsh conditions. Its patented internal compensating diaphragm (ICD) compensates for temperature and pressure changes, ensuring reliable performance in deep-water applications. Additional features include a white-on-black dial, stainless steel internals, and freeze-proof KEM-X Socket Savers. With the option for NIST traceable certifications, this versatile gauge is essential for high-pressure applications where precise readings are critical.
