Germany is written on the pressure gauge itself, with a hint of the manufacturer, but he made, of course, in China.
Although the quality is good. He took measurements, drove to a couple of gas stations with tire inflation machines and immediately checked with the readings of the pressure gauge, if he was lying, then only by 0.1 atmospheres, no more.
It works for me as it should, regularly, after pumping the wheels with a compressor, I check the pressure, everything is ok.See full review
