☆ ☆ PM-2 vacuum gauge maintenance and maintenance:
1. When transporting and using, it must be prevented from lying upside down. Water-repelling silver is poured back into the vacuum like the inside of the tube or the mercury beads enter the capillary tube in the middle of the closed tube to affect the measurement accuracy. Therefore, the vacuum hose must be set upright before each use to allow the mercury to flow back into the vacuum gauge glass tube.
2. When measuring, the vacuum gauge is in the upright state. It is forbidden to rush any gas into the vacuum system so as not to impact the glass tube to break the glass tube.
3. Mercury in the vacuum gauge has been treated by chemical physical methods and has certain cleanliness. Mercury oxidation caused by long-term use and other reasons will directly affect the measurement accuracy, should be promptly sent to the repair, can be used after inspection.

This keeps the mercury inside the vacuum gauge clean and also prevents the vacuum from breaking down when the vacuum gauge is removed. If the vacuum gauge is not taken down, the mechanical pump must be disconnected from the vacuum system after the mechanical vacuum pump is stopped, and the mechanical pump should be put into the atmosphere to prevent the mechanical pump oil from returning to the vacuum system and the vacuum gauge receiving oil. Pollution. After that, it is necessary to disconnect the mechanical pump from the vacuum system air circuit, and put the mechanical pump into the atmosphere to prevent the mechanical pump oil from returning to the vacuum system and the vacuum gauge being contaminated by the oil.
