Pressure gauge with adapter

acquired a dinghy -mariner Intex 4, actually a practical help to control the air pressure in the individual chambers. everything fits and funktionier, but it must be read at the same time my inflate. going quite well after some time of getting used to if as the gross manometereinteilung would not. 0.8 bar read is already problematich and you will certainly never managed exactly. but otherwise a good unit to prevent internal pressures far beyond the manufacturer's instructions.
