Span gauges are designed for rugged service applications. Liquid fill fluid dampens the gauge pointer movement for
improved readings and longer life, making these gauges ideal for high shock and vibration applications. Its Zytel case
and ring offer good appearance and excellent resistance to chemical, weather, and corrosion attack.
