Zirconia oxygen analyzer notes - Database & Sql Blog Articles

1. The sample gas needs to be pressure-controlled, usually the pressure of the instrument should not be greater than

0.05MPA;

2. The output pressure of the standard secondary meter shall not be greater than

0.30MPA;

3. All gas pipelines entering the zirconia oxygen analyzer must undergo strict leak detection, and this work must be performed once every six months when the instrument is working normally.

;

4. Before the gas path enters the instrument, it must pass through the physical filter.

10u;

Found a gas barrier phenomenon, you can check the filter first.

5. Clean the analyzer fan filter regularly, once a quarter

;

The environment is bad and needs to be cleaned frequently to prevent overheating of the instrument due to poor ventilation.

;

6, the installation site of the instrument should be horizontal, away from the vibration source

;

To prevent errors caused by uneven convection of the sample caused by the detector not being level

;

7, the surrounding environment of the zirconia oxygen analyzer requires good ventilation, avoid confined space, measurement error caused by imbalance of oxygen

;

8. There should be no flammable gas around the analyzer, which will seriously affect the accurate measurement of the detector.

;

9. Since the test is operated at high temperature, if the gas to be tested contains

H2

with

CO

,

CH4

At this time, the substance reacts with oxygen, consumes part of oxygen, and the oxygen concentration decreases, causing measurement errors. Therefore, the instrument should consider this factor when measuring the gas containing flammable substances to avoid measurement misalignment.

10. When measuring corrosive gases, filter with activated carbon.
