CEMS Online Infrared Syngas Analyzer O2 Trace Analyzer
Zetron ZN301 Online Trace Oxygen Analyzer
ZN301 Trace Oxygen Analyzer is a new-type intelligent industrial online analyzer researched and developed by combining imported high-performance electrochemical sensor with new microcomputer technology based on the principles of electrochemical detection.
- Imported fuel cell sensor adopted, featuring long service life, high accuracy, and quick response;
- Chinese human-machine dialog menu, making operation intuitive and convenient;
- Timed automatic storing function, and stored data available for viewing at any time;
- Automatic range shifting; alarm point can be set at will within the whole range;
- Standard RS232 or RS485 communication interface available for two-way communication with computer;
- Built-in air extracting pump and external filter can be added upon selection;
- Type B adopts economical 128×64 lattice LCD; type C uses engineering 320×240 lattice LCD; and type D employs intelligent 800×400 touch screen in combination with embedded RAM technical instrument
