High-Accuracy Low-Pressure Gauges

Single Scale With Bottom Connection

Single Scale With Center Back Connection

Dual Scale With Bottom Connection (Flange Mount)

Bottom Connection

Center Back Connection

Bottom Connection (Flange Mount)
Measure small pressure changes in ventilation systems, hydraulic applications, and other critical processes with these high-accuracy gauges. Mount them with the dial face upright.
Gauges with 304 stainless steel case or polyester plastic case have better corrosion resistance than gauges with steel case.
Gauges with safety case blow out in the back under excess pressure, protecting the operator in front.
