4.5" Plastic Case Premium Pneumo Gauge

The Ashford Instrumentation Ltd 4.5" diameter ABS plastic case multiport premium pneumo gauge is a precision pressure gauge used for diver depth monitoring or for measuring the pressure within a hyperbaric chamber. This Premium Pneumo Gauge features the ability to zero the pointer via an adjustment screw located on the front of the gauge as well as having a Full Safety Pattern design case and is ideal for commercial diving applications where oxygen or enriched air is being used. With an accuracy of 0.25% full scale, an easy to read mirror band dial and knife edge pointer, our Premium Pneumo Gauge is built to the highest engineering standards.

The Premium Pneumo Gauge is fully degreased and the dial is marked with the crossed oil can symbol in red. Optionally the word OXYGEN can also be added. Please note that as sea water scales do not have an Internationally recognized value all of our instruments are manufactured with a sea water specific gravity value of 1.025 which is marked on the dial.

The gauge has the following features:

Multi-Port Design - Lower Back of Bottom Entry Interchangeable
Removeable & Changeable Coloured Front Flange For Easy Identification
Easy Change Process Thread Connection
Dimensionally Identical & Interchangeable With 3D Instruments Design

As standard this instrument is supplied as 3-hole front flange with lower back entry although a bottom entry port is also provided as standard.
