Instrument features:

• Chinese English menu switching function, intuitive and convenient operation；
• 320×240 graphic dot matrix color LCD display, with delicate and clear display;
• Adopting imported fuel cell sensors, it has the characteristics of fast response speed, high measurement accuracy, long calibration cycle, and strong resistance;
• Adopting a protective air path of * effectively protects the sensor and avoids the sensor's lifespan being affected by prolonged exposure to air;
• Built in sensor protection device and temperature compensation sensor ensure the service life of the sensor while reducing the impact of changes in sample gas temperature and environment on measurement accuracy;
• Calibration at any point within the entire range is sufficient, without the need for multi-point calibration, making calibration simple and convenient;
• 40000 piecesAutomatic data storage function, users can view historical data locally at any time;
• According to user needs, RS232 (default) or RS485 data communication interfaces can be optionally configured，Can be used with computersOr other digital communication devices directlyPerform one-way or two-way communication.

Application scenarios:

Widely used in online oxygen analysis industries such as petrochemicals, air separation, semiconductor industry protective gas detection, food production process gas detection, and oxygen concentration detection in hydrocarbon gases.
