Noshok’s 1000 Series Differential Pressure Gauge features a simple yet rugged piston-type mechanism ideal for measuring pressure differences from 5 psid to 110 psid. Designed with a tough engineered plastic case, it withstands harsh operating conditions while maintaining a lightweight form factor. Wetted components include clear anodized aluminum and 316 stainless steel for corrosion resistance and long-term durability. The gauge is available in 2-1/2", 4-1/2", and 6" sizes, offering flexibility for various installation spaces. It is ideal for monitoring backflow, filters, flow systems, and level indicators in fluid handling processes.

The Noshok 1100 Series Diaphragm Type Differential Pressure Gauge is engineered for applications where diaphragm sensing provides advantages over piston types—especially at lower pressure ranges. It offers a measurement range from as low as 0 inH?O up to 100 psid, allowing for accurate differential readings in sensitive systems. The standard black anodized aluminum housing is lightweight and corrosion-resistant, while 316 stainless steel is also available for more aggressive media compatibility. Its engineered plastic gauge case houses dial sizes of 2-1/2", 4-1/2", and 6", offering flexibility in installation. This gauge is ideal for monitoring filters, backflow, level, and flow conditions in HVAC, water treatment, and process systems.

• Filter condition monitoring, heat exchangers, flow measurement, water systems, backflow detection, and level indication.
