- 1785 Series Gauges
Model 1785 2-1/2” Manifold Pressure Test gauges offer several ranges for use with various types of refrigerants, including R-12, R-22, R-502, R-134A, and R-410A.
- P1521 1-1/2” Corrosion Resistant Pressure Gauges
The compact Model P1521 is an all-stainless steel pressure gauge featuring Type 316L SST internal wetted components and a polished 304 SST case to withstand corrosive media and atmospheres. These gauges are ideally suited for industrial and specialty gas applications.
- P1522 2” Corrosion Resistant Pressure Gauges
The Model P1522 is an all-stainless steel pressure gauge featuring Type 316L SST internal wetted components and a polished 304 SST case to withstand corrosive media and atmospheres. These gauges are ideally suited for industrial and specialty gas applications.
- C-1706K Series Gauges
2-1/2” and 3-1/2” steel case gauges, usually installed in ammonia refrigeration systems, these C-1706 compound gauges can also be used to handle other chemicals not injurious to wetted parts. The silicone dampened movement greatly extends gauge life, particularly on tough services like ammonia compressors. Temperature equivalent scale in red provides easy analysis of refrigeration systems.
- PT-1088 Series Boiler Gauges
The PT-1088 Series boiler gauges are designed for low cost, reliable pressure and temperature measurement in a wide range of applications.
- P-733 & P-734 Series Diaphragm Gauges
P-733
These high quality diaphragm gauges feature rugged construction with high sensitivity. They are ideally suited and designed for pressure measurements below 15 psi.
P-734
These gauges feature a highly sensitive diaphragm for extremely low
positive or negative pressure applications. Gauges are housed in a rugged steel case with screw-in, acrylic window. The low mount connection is 1/4-18 NPT, brass.
- 300 & 310 Series Air Volume Controls
U.S. Gauge Air Volume Controls are designed for domestic water supply systems which deliver a quantity of air to the pressure tank with each cycle of pump operation. Insufficient air in the pressure tank causes frequent operation of the pump. Too much air in the pressure tank will permit large bubbles to be carried into the piping system. This causes a disagreeable noise and sputtering at the faucets. It is the function of U.S. Gauge air volume controls to maintain the correct relationship between the volume of air and the quantity of water in the pressure tank.
