Electrochemical oxygen analyzer test procedures
1 Scope
The order applies to oxygen measurement limit of not less than 0.1% of electrochemical oxygen analyzer initial verification, follow-up inspection
Set and test use. Not for use in electrochemical oxygen analyzer used in the mine.
2 Overview
Electrochemical oxygen analyzer (hereinafter referred to as equipment) is mainly used in chemical industry, metallurgical industry, environmental monitoring, medical
Health, aerospace, gases and oxygen content in the ambient air measurement electronics industry in the production and application. Class
Equipment for electrochemical principles, including. Galvanic (fuel cells, batteries Hertz diaphragm galvanic cell), constant power
Bit cell, the cell constant current, Coulomb, polarography and other electrochemical principle Oxygen gas detection unit
Analyzer.
The instrument usually consists of an electrochemical oxygen sensor (liquid or solid electrolyte), gas unit and the electronic display unit group
to make. Based on gas sampling way into the pump suction type, positive pressure conveying type, three types of diffusion. Measurement procedure in Figure 1

3 metering performance requirements
3.1 Scope and instrument indication error
Different range of instruments, within its measuring range, indication error corresponding to comply with Table 1.
Table 1 shows the instrument range and error
Instrument Range /% indication error /% FS
≤25 ± 2.0
> 25 ± 3.0
Note. "FS" as being a full-scale inspection of the instrument.
3.2 Repeatability
The relative standard deviation ≤1%.
3.3 Response Time
Inhaled, positive pressure conveying type instrument response time of less than 30s; the proliferation of instruments is not more than 60s.
