Y series general pressure gauge

◆ Model: Y40 Y50 Y60 Y75 Y100 Y150 Y200 Y250
◆ Use: This series of instruments is suitable for measuring the pressure of liquid, gas or steam which has no danger of explosion, does not crystallize, does not solidify, and has no corrosive effect on copper and copper alloy.
◆ In practical application, according to the special characteristics of various media (such as oil ban, fire prevention, corrosion resistance, etc.), the requirements of the instrument are different, so this series of instruments derive many corresponding special instruments, their nominal diameter, installation type, connector thread, accuracy level, measuring range, etc. are the same as the general pressure gauges, and there are mainly two categories:
1.1 Suitable for measuring the pressure of flammable and explosive media. It is strictly prohibited to contact with greasy flammable substances. Degreasing treatment is made before leaving the factory, and it is tested for no grease.
1.1.1 YO series oxygen pressure gauge
1.1.2 YH series hydrogen pressure gauge
1.1.3 YY series acetylene pressure gauge
1.2 The materials used are resistant to the corrosion of the medium or the instrument has no influence on the medium, and ensure that the detecting elements and interfaces are clean and free of grease.
1.2.1 YA series ammonia pressure gauge
1.2.2 YDq series nitrogen pressure gauge
