Pressure Gauges

3-A approved diaphragm pressure gauge designed for the demanding yet abusive environment of most food processing plants. This is not an industrial gauge with a diaphragm seal assembly, the Sani-Flow pressure gauge has been designed specifically for sanitary applications. The gauges are extremely accurate yet durable and are available with sanitary fittings in sizes from 1-1/2" to 3", and pressure ranges from 30"Hg (vacuum) up to 1,000 psi. Our Sani-Flow pressure gauges are generally in stock, and ready for same day shipping in almost any configuration.

This is our most economical gauge which we designed specifically for the brewery industry. They are constructed with an all Stainless Steel case and are available with either a 1-1/2" or 2" Tri-Clamp fitting. The gauges are very accurate yet durable for the typical environment in a brewery. This gauge is offered in many different scales with pressure ranges from 30"Hg (vacuum) up to 1,000 psi. Please see our product configurator page to help choose style and options and obtain a part number.

Designed for chemical processing applications where exposed stainless steel can not be tolerated. The Chem-Flow pressure gauge has the accuracy, durability and reliability of our Pharma-Flow series plus a PTFE coated fitting/diaphragm and an impact resistant tempered glass lens. The result is the highest quality, longest lasting diaphragmed pressure gauge available for harsh chemical processing.

More than 30 years of experience in designing and building sanitary pressure gauges has gone into engineering an exceptional gauge designed specifically for homogenizer applications. Internal dampening means little or no pointer oscillations and much longer gauge life. Like the rest of our products, the homogenizer gauge was conceived with accuracy, durability and low cost of maintenance in mind. The gauge is available in pressure ranges from 1,000 psi up to 15,000 psi, with or without the 2 bolt flange. The Sani-Flow homogenizer pressure gauge is delivered from stock in just about any configuration.

3-A approved diaphragm pressure gauge designed specifically for the stringent requirements of the pharmaceutical industry. The Pharma-Flow line is the most accurate sanitary pressure gauge available. It is also the cleanest, a flush mounted diaphragm and no sharp corners or crevices to harbor possible contaminates. They are available in most sanitary fitting in sizes from 1-1/2" up to 3" and in pressure ranges from 30"Hg (vacuum) to 1,000 psi. As with our other products, the Pharma-Flow pressure gauge is delivered from our extensive stock in just about any configuration.

An all stainless steel industrial pressure gauge with NPT connections. Offered in either a 2-1/2"(63mm) or 4"(100mm) dial face. The 2-1/2" gauges are available with 1/4"NPT connections and 4" gauges are available with either 1/4" or 1/2"NPT. These are constructed with a stainless steel case, socket, tube and movement. They are available in pressure ranges from 30"Hg vacuum (-1 BAR) to 10,000 psi (700 BAR). Most Insta-Flow gauges are in stock and ready for same day shipping.

Chicago Stainless Equipment offers a high quality line of Stainless Steel, Carbon Steel, and Brass pressure gauge Siphons. They are available in several different configurations. Also known as pigtails, use a siphon tube to protect non-sanitary pressure gauges from the effects of rapid pressure surges and steam and high-temperature fluids. Also use siphons whenever condensing hot vapors (not just steam) are present. Add water to the tube to make a protective barrier between your gauge and process media.
