DUOTIGHT 8MM (5/16) DIGITAL ILLUMINATED MINI GUAGE UPGRADE - 0-90PSI (0-6.2BAR)

Traditional analogue gauges require a small capillary mechanism where a small pipe expands and unravels under pressure.  This in turn drives a mechanical cog to rotate the gauge needle.  This age old technique works quite well especially in large gauges but as this mechanism is manufactured smaller and smaller a tradeoff between accuracy and size becomes the issue. With very small gauges such as a 27mm x 27mm Mini Gauge it's difficult to make them better than 10% accuracy due to the physical constraints of the mechanical components.

This very compact design retains high accuracy while still meeting the desirable small form factor.  This meets the growing need as mini keg systems, mini regulators and other more compact keg dispensing solutions is required.

Specifications:
Battery Life: More than 2 years (using the mini gauge once a day)
Battery Type: CR2032
Auto Battery Saver: YES, screen automatically turns off after 15sec
Size: 27mm x 27mm
Radial O-ring Stem: 7.8mm Bore

NOTE:  This gauge is not suitable for measuring pressure of liquids.  It is only for measuring gas pressure.  If liquid gets into the pressure transducer it will damage the gauge.  

This digital mini gauge can be used to upgrade your:
Blowtie Spunding Valve
Mini Inline Regulator

If you would like to use the mini gauge to attach to other hobbie projects then you should consider the Duotight Compatible Digital Mini Gauge that has the 8mm duotight push in stem. This makes it easy to fit to other 8mm duotight fittings, tubing etc.
