Online Infrared Syngas Analyzer 300ml/Min Nitrogen Purity Analyzer With Electrochemical Sensor
Zetron ZN311A Online Nitrogen Purity Analyzer
ZN311A Nitrogen Purity Analyzer is a new-type intelligent industrial online analyzer researched and developed by combining imported high-performance electrochemical sensor, which is used to detect oxygen and display nitrogen purity, with new microcomputer technology.
- Imported fuel cell sensor adopted, featuring long service life, high accuracy, and quick response;
- Small volume and lightweight, making the instrument especially suitable for places where the installation space is relatively small;
- Automatic range shifting; upper/lower limit alarm can be set at will within the whole range;
- Alarm point can be set at will within the whole range;
- RS232 or RS485 communication interface available for two-way communication with computer.
