US Gauge P-733 / P-734 Low Pressure Gauge

The US Gauge P-733 and P-734 Low Pressure Gauge are high sensitivity diaphragm gauges designed for low and negative pressure applications, ideally below 10psi. Variable low pressure measurements are available with both models for the same cost, from static pressure(inH2O) to ounces (oz/in^2) to gauge(psi). A dual scale for measurement of both ounces per square inch and inches in water is available upon request.

The P-733 features a low mount style, the P-734 with a center back mount, both models hosting a brass 1/4-18 NPT process connection. The durable housing of steel is coated in corrosion-resistant paint, with a twist-in polycarbonate window for easy maintenance and long service life.
