Our custom made pressure gauges have a range from 0-100kpa with indication every 2kpa. 

We have added a red line at 25kpa (recommended pressure for pontoons and kelson). 

They come with a protective shock cover and on the back we have attached a "ShockWatch" sensor that will change colour when dropped from greater than 1m to indicate that it might be damaged or need re-calibrating. 

The lens is removable to allow for calibration if required.

Bay bridge valve adapter included. This adapter can also be used on the end of a air compressor, and in a foot or hand pump hose.
