Stewarts 400 Series Pressure Gauges

Stewarts 400 series gauges are high quality pressure gauges suitable for general purpose applications where reliability is key.  The 400 series of gauges are suitable for gas and liquid media which do not corrode brass or have an environment which is not harsh to Mild Steel o Aluminium case. This model is commonly used on equipment like pumps, compressors, boilers, pneumatic and hydraulic machines.

This gauge has a blow-out protection and weatherproof construction to IP54. All units are manufactured to comply with EN-837, S1 or S3 specification and other regulatory standards including PED 2014/68/EU. Fluidic hold an exclusive partnership with Stewart Buchanan gauges for representation in the UK nuclear industry.
