Stewarts 600 Series SS Pressure Gauges

Stewarts 600 series gauges are high quality pressure gauges suitable for industrial applications where reliability is key.  The 600 series of gauges are suitable for gas and liquid applications.  Material of construction is predominantly 316SS (wetted and non-wetted parts) for suitability with chemically demanding environments.  (For extremely aggressive media consider chemical seals, which are also available through Fluidic supplied assembled to the instrument).

Typical applications include: petrochemical, refineries , the power industry, marine, food and pharmaceutical and on and offshore oil and gas.  Fluidic hold an exclusive partnership with Stewart Buchanan gauges for representation in the UK nuclear industry.
