Low Pressure Capsule Gauges

GNW’s low pressure (also known as capsule) gauges are used for measuring gases at low pressures or vacuum.

Capsule gauges utilise a sensitive bellows element rather than a standard bourdon tube element enabling them to measure accurately at very low pressure or vacuum operating levels.

They are suitable for measuring very low pressures in ducting and filters and also for use on industrial machinery.

Enamelled case, acrylic window gauges are available as standard. We can also manufacture all stainless steel, glycerine filled or large diameter capsule gauges on request.

Our capsule gauges are available in 63, 80, 100 & 150mm diameters. Bottom entry, back entry, direct mounting, surface mounting and panel mounting options are all available.
