氧气压力表检定在操作上与压力表相同,但氧气压力表禁油,给检定工作带来一定难度。目前大致采用三种方法来解决这个问题。比较如下: 1.用*作为传递介质此法绝对安全,但水极易锈蚀校验器。另外,由于水粘度低,检定高压氧气表如25MPa,既易泄漏,压力又上不去。 2.用甘油作为传递介 Oxygen pressure gauge verification in operation with the same pressure gauge, but the oxygen pressure gauge ban oil, to the verification of a certain degree of difficulty. At present, roughly three ways to solve this problem. Compare as follows: 1. Use * as the transmission medium This method is absolutely safe, but the water is very easy rust checker. In addition, due to the low viscosity of water, high pressure oxygen gauge test such as 25MPa, both easy to leak, the pressure can not go up. 2. With glycerol as a transfer agent
