Marsh Gauges can handle harsh chemicals, oils, food and beverage, high pressures, and many more applications. The come in a wide range of materials of construction for your compatibility needs.

• Pressures up to 20,000 psi
• Sizes up to 6”

Diaphragm Seals

Marsh Diaphragm Seals isolate pressure gauges and other instruments from the process flow to allow the instruments to accurately measure pressure. They can also extend the life of instruments and reduce maintenance downtime by protecting from corrosion, clogging, freezing, or pulsation damage. Available in a variety of material options including both rubber and weld diaphragm seals.

• Pressures up to 2500 psi
• Sizes up to 4.5”

Digital Pressure Indicators

Marsh Digital Pressure Indicators are portable, lightweight, handheld, testing and calibration instrument that can read pressures up to 50 psig to an accuracy of +/- 0.25% of reading +/-1 count. Design of the digital pressure indicator incorporates a state-of-the-art semiconductor-type pressure transducer which converts pressure input to analog voltage, outputted to a 3.5 digit LCD readout display.

Filter, Regulator, Lubricator

Marsh Filter, Regulator, Lubricators (FRLs) are a pre-packaged, fully configurable modular assembly of common air filters, regulators, lubricators, and gauges configurations sold as a single unit.
