Brief introduction to product

 DY series of electrochemical oxygen analyzer adopts the imported U.S high quality oxygen sensor with high performance, it has a rapid response time and a long-term using life, can meet both analysis and inspection of percentage composition, PPM and PPB order. Direct at different gas environment, the sensor adopts electrolyte membrane technology, and then combines with ARM embedded system, so that it can be applied in real-time measurement and analysis of oxygen concentration of these gases such as pure gas, inert gas and special gas (acid or alkaline environment), etc in different environments for measurement. The instrument can combine with flow control, temperature compensation and pressure control system, showing the better human-computer operating flatform and the wide service performance.

Application Range

1.Air separation industry: analysis of oxygen content in nitrogen, argon and inert gas

2.Metallurgical industry:Analysis of oxygen content in blast Furnace gas, converter gas and shielding gas for smelting

3.Petrochemical industry, bio-fermentation: analysis of oxygen content in special technique links (such as oxygen content analysis of electrolytic hydrogen and compost

4.Semiconductor chip, electronic manufacturing industry: analysis of oxygen content in shielded arc welding or shielding gases;

5.Food and beverage: analysis of oxygen content in CO2

6.Coal chemical industry:Analysis of oxygen content in coal gas

Charateristics of Product

1.Analyze the oxygen content fast and precisely; standard 19-inch cabinet / mini coil cabinet/ portable case can integrate with microcomputer and PLC into one analytic system;

2.High versatility, multipurpose;

3.Suitable to on-line process analysis and portable analysis

4.Power-on self-test, run stably, needing no maintenance;

5.The sensor possesses actual zero point and can provide zero output in oxygen-free environment without calibrating gas at zero point;

6.Accurate surveying from %(10-2) to level ppb(10-9);

7.Application of membrane technology enables the analyzer to work stably in acidic gas or other special gas environment for a long time.
