"Standard Pneumo" Depth Gauge - Breathing Air (Diameters 150mm to 300mm)

The Ashford Instrumentation Ltd Standard Pneumo Gauge is a  precision pressure gauge used for diver depth monitoring or for measuring the pressure within a hyperbaric chamber offering the ability to zero the pointer via an adjustment screw located on the front of the gauge.

Available in 150mm, 200mm, 250mm, 300mm and 8.5" diameters with a black powder coated steel case and 160mm diameter with a 304 stainless steel case, the Standard Pneumo Gauge is fully degreased and is designed for commercial diving applications where breathing air is being used. With an accuracy of 0.25% full scale, an easy to read mirror band dial and knife edge pointer the Standard Pneumo Gauge is built to the same high standards as our Premium Pneumo Gauge but does not feature the full safety pattern case required for oxygen service or for applications in Europe where the instrument range exceeds 25 Bar (250 Meters Sea Water). 

The Standard Pneumo Gauge is fully degreased and the dial is marked with the crossed oil can symbol in red and the wording USE NO OIL. The European Standard EN837-1 is also marked on dial on ranges to 25 Bar. As sea water scales do not have an Internationally recognised value all of our instruments are manufactured with a sea water specific gravity value of  1.025 which is marked on the dial.

As standard this instrument is supplied as 3-hole front flange with lower back entry although panel mount clamp fixing and surface mount with 3-hole back flange mount is also available. Bezels can be manufactured in a range of powder coated colours including red, green and yellow.

Please note that according to the European Standard EN837 - 1, gauges used on gas or air applications above 25 Bar or on any oxygen service regardless of the pressure range should be of a safety pattern "S3" design which includes a solid baffle wall and blow out back. We do not recommend this gauge for oxygen use or for use on applications above 25 Bar.

If the gauge is to be used on an oxygen application or if to be used in Europe with a range above 25 Bar (250 Meters Sea Water) we strongly suggest you use our Premium Pneumo Gauge.
