1 Scope

This procedure is applicable to zirconia oxygen analyzers (hereinafter referred to as instruments) with a lower limit of oxygen content measurement of not less than 0.1%. First verification, follow-up verification and in-use inspection.

2 Overview

The zirconia oxygen analyzer is mainly used to detect the oxygen content in the mixed gas to achieve safety and festival of the production process. Energy, environmental protection and the purpose of ensuring product quality. The working principle of zirconia oxygen sensor. after adding a certain amount of stabilizer by zirconia material, it is burned by high temperature. It becomes an oxygen ion solid electrolyte at a certain temperature. Baking the platinum electrode on both sides of the material to form a zirconia transmission Sensor, when the oxygen content between the electrodes on the two sides is different, an electromotive force is generated between the two electrodes, which constitutes an oxygen concentration battery, and two electricity The interpolar reaction is as follows. Cathodic reaction. O2 4e→2O2- Anode reaction. 2O2-→ O2 4e The zirconia oxygen analyzer uses this characteristic of the zirconia sensor to convert the oxygen in the detected environment into The electrical signal is then processed by the electronic components and displayed as a concentration value.

3 Metrological performance requirements

3.1 indication error Measuring range. Molar fraction of oxygen x (O2). 0.1% to 100%; allowable error limit. ± 5% FS. Note. For oxygen, the volume fraction is approximately equal to the mole fraction. 3.2 Repeatability The relative standard deviation should be no more than 1.5%. 3.3 Response time Response time ≤ 20s 3.4 Drift 3.4.1 Zero drift The instrument is continuously operated for 4 hours, and the zero drift should not exceed one-half of the allowable error limit. 3.4.2 Range drift The instrument runs continuously for 4 hours, and the range drift should not exceed one-half of the allowable error limit.

4 General technical requirements

4.1 Appearance 4.1.1 The instrument shall indicate the name of the manufacturing unit, the model and serial number of the instrument, the date of manufacture, and the manufacturing license for measuring instruments. ......
