Portable high oxygen analyzer (core function: fast and accurate detection of oxygen concentration in the environment or gas, suitable for high oxygen scenarios, measurement range usually 0-30% Vol/0-100% Vol, some models support trace oxygen detection) With "portability+high sensitivity+anti-interference", it is widely used in industrial production, environmental protection and safety, scientific research experiments and other fields. The specific scenarios are as follows:
1、 Industrial production field (core requirements: process control, safety protection)
Chemical and petrochemical industries: used for oxygen concentration monitoring in synthesis reactions, catalytic reactions, and other processes (such as controlling oxygen purity above 95% in oxidation reactions to avoid incomplete or excessive oxidation); Simultaneously monitor the residual oxygen after the replacement of sealed reaction vessels and storage tanks (such as oxygen concentration ≤ 1% Vol after inert gas replacement to prevent explosion risks), and adapt to on-site inspection needs.
Metallurgy and Heat Treatment: During high-temperature smelting and metal heat treatment processes, monitor the oxygen concentration of protective gases (such as nitrogen+oxygen mixed gases) to ensure that metal materials are not oxidized (such as controlling the oxygen concentration below 0.1% Vol during stainless steel annealing); The portable design can flexibly adapt to the rapid inspection of different workstations in the workshop.
Electronic semiconductor manufacturing: In processes such as wafer cleaning and packaging, monitor the purity of high-purity gases (such as oxygen and nitrogen) to avoid excessive oxygen concentration leading to chip oxidation failure; Some high-precision models can detect ppm level oxygen content, meeting the stringent process requirements of the semiconductor industry.
Food processing and packaging: detecting oxygen concentration in modified atmosphere packaging (MAP) (such as fresh food packaging with oxygen concentration ≤ 2% Vol, extending shelf life); Simultaneously used for monitoring oxygen content in food freeze-drying and baking processes to prevent food oxidation and spoilage, suitable for production line inspection and warehouse sampling.
2、 Environmental protection and safety field (core requirements: leak detection, emergency rescue)
Safety of confined space operations: Before entering confined spaces such as underground pipelines, storage tanks, mines, etc., rapid detection of oxygen concentration (normal oxygen concentration 19.5% -23.5% Vol) is necessary to avoid safety accidents caused by oxygen deficiency (<19.5% Vol) or oxygen enrichment (>23.5% Vol). It is an essential safety detection tool before operations.
Gas and energy industry: Monitor oxygen leakage in natural gas, coalbed methane and other gas transmission pipelines (abnormal increase in oxygen concentration may indicate pipeline damage); At the same time, during the maintenance of gas combustion equipment (such as boilers and kilns), the oxygen concentration in the furnace should be detected to prevent maintenance personnel from experiencing oxygen deficiency or explosions caused by gas mixing with air.
Fire emergency rescue: In the event of a fire or chemical leakage accident, rescue personnel carry instruments to quickly detect the concentration of oxygen in the environment, determine whether there is a risk of oxygen deficiency or enrichment, and provide a basis for developing rescue plans; Some explosion-proof models can be used in flammable and explosive environments.
