The SPAN Liquid Filled Subsea Gauge is a durable and reliable pressure gauge designed for use in demanding environments like subsea, ROV equipment, military, and marine applications. Available in 2.5", 3.5", and 4.5" sizes, it features a liquid-filled design that dampens pointer movement, improving accuracy and extending the gauge's lifespan, even in high-shock and vibration settings. The Zytel case and ring offer exceptional resistance to chemicals, weather, and corrosion, making it ideal for underwater and harsh conditions. Equipped with a patented internal compensating diaphragm (ICD), the gauge compensates for temperature and external pressure fluctuations, ensuring stable readings in deep-water applications. Additional options include a freeze-proof KEM-X Socket Saver, and all gauges can be serialized and certified to NIST standards for accuracy.
