The Ashford Instrumentation Ltd 4.5" diameter ABS plastic case multiport premium therapeutic gauge is a precision pressure gauge typically used for medical applications within a therapeutic chamber.
This premium therapeutic gauge features the ability to zero the pointer via an adjustment screw located on the front of the gauge and is ideal for commercial diving applications where an accuracy of 0.25% full scale is required. With an easy to read mirror band dial and knife edge pointer, our therapeutic gauge is built to the highest engineering standards.
The therapeutic gauge is fully degreased and the dial is marked with the crossed oil can symbol in red.
Optionally the word OXYGEN can also be printed on the dial. In this instance we have the option of manufacturing the gauge with an internal solid baffle wall and large blow out back to meet the safety requirements as defined by the European Standard for Pressure Gauges EN837 S3 Safety.
Technical Note: OXYGEN. IMCA D 022 Rev 1 (May 2014) Chapter 9 Gas Handling Section 9.6 notes that "Any gas mixture containing more than 25% oxygen by volume should be handled like pure oxygen". The 2023 IMO Diving Code lowers this threshold concentration for oxygen enriched environments from 25% oxygen (1995 code) to 22% oxygen (2023 code). Based on this information we recommend any application where the concentration of oxygen is enriched above 22% should be treated as a pure oxygen application.
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 Comparable & Interchangeable With 3D Instruments Design
Transit Lock Screw Fitted
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. To adjust from back entry to bottom entry simply remove the thread adaptor and screw into the bottom port. Surface mounting with 3-hole back flange mount is also available via optional additional flanges. Bezels can be manufactured in a range colours including red, green, and yellow.
The 4.5" diameter therapeutic gauge can also be supplied from the factory with a rear panel mounting clamp option and narrow front bezel if required.
The premium therapeutic gauge is also fitted with a Transit Screw located on the back of the case. The screw turned turned through 45 degrees to lock/unlock, operates a mechanical lock which holds the bourdon tube in position preventing unwanted movement/damage during transportation.
