High-Accuracy Low-Pressure Gauges




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.
