YU-6/6B/60A/600/600A series piston pressure gaugeDetailed product description：

The YU-6/6B/60A/600/600A series piston pressure gauge is a pressure standard instrument, mainly suitable for calibrating precision pressure gauges with accuracy below 0.25 level, and can also be used to calibrate lower level piston pressure gauges, various industrial pressure gauges or other pressure measuring instruments. The pressure gauge is suitable for working under conditions of ambient temperature of 20 ± 5 ℃ and relative humidity not exceeding 80%.
