Large-Dial High-Accuracy Pressure Gauges
Single Scale With Bottom Connection (Flange Mount)
Dual Scale With Bottom Connection
Bottom Connection (Flange Mount)
Read your pressure from a distance with these large-dial gauges. 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.
Gauges with aluminum case have better corrosion resistance than gauges with steel case.
