YU series Piston pressure gauge

YU series Piston pressure gauge is pressure standard instrument which is used to calibrate precise pressure gauge which the accuracy is lower than 0.25 grades. It also can calibrate the lower grade of piston pressure gauge, industrial pressure gauge and other pressure measuring instruments. The working temperature is 20±5℃ and RH is no more than 80%.
