Proof oxygen pressure gauge, what should be paid attention

oxygen pressure gauge should pay attention in school what? Since encountering oil will cause an explosion of oxygen, wood, school team is strictly prohibited when oxygen pressure gauge with oil as the coolant, oil-water separator should be used. Will always have the pressure gauge calibration error, there will be the following:

1, was school pressures on each checkpoint represents high or low a fixed value, then the pointers do not fit exactly, pointer should be established.

2, was school pressures that value as the pressure increases, and higher.

3, the pressure value is too low, then check low pressure increases, the more serious. You must select at least precision pressure gauges.

4, school pressure gauges low pressure normal, with increased pressure deviating.

5, if the pressure gauge on the minimum scale indication deviation of direction, decreasing with the increase pressure, should release the retention screw clockwise movement of movement at an angle.
