Get instant pressure reads with the back-illuminated Digital Mini Pressure Gauge from KegLand. Compatible with 8 mm Duotight fittings and Gray Ball Lock QDs. If you're using the original BlowTie spunding valve without a pressure gauge, you can use a Duotight tee fitting in-line between the ball lock QD and the BlowTie to take pressure readings with the Digital Mini Gauge.
KegLand has developed the world's most compact mini digital gauge with backlight illumination. 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 are required.
Traditional analog 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.
Please 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.
