About Pressure Gauges

About Pipe Size

Bottom Connection (Flange Mount)

Sensitive enough to operate on indoor light, these gauges have no batteries to replace. They have a four-digit LCD display for easy reading of measurements. Gauges are rated IP65 for protection against water projected from a nozzle. They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications.

Lower Back Connection (Flange Mount)

Built for harsh environments prone to vibration, these gauges pair a corrosion resistant stainless steel case and connection threads with a glycerin-filled dial to reduce needle flutter. Use them with pumps, filters, regulators, and in process lines to measure and display pressure. They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications. Mount gauges with the dial face upright.
