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.KegLand has developed the worlds 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 is required.Specifications:Battery Life: More than 2 years (using the mini gauge once a day)Battery Type: CR2032Auto Battery Saver: YES, screen automatically turns off after 15secSize: 27mm x 27mmDuotight Stem: 8mm
