Wall mounted oxygen analyzerInstrument features:

The use of imported fuel cell sensors has the characteristics of long service life, fast response time, high detection accuracy, and long calibration cycle;

Adopting DT's protective air path effectively protects the sensor and avoids the sensor's lifespan being affected by prolonged exposure to air;

Calibration at any point within the measurement range is sufficient, without the need for multiple calibration points, to meet the measurement accuracy of the entire range;

Built in temperature compensation function, eliminating the impact of environmental temperature changes on sensor measurement accuracy;

Automatic data storage function and the ability to access historical data at any time;

The function of switching between Chinese and English menus is intuitive and convenient to operate;

Automatic blowback function (optional), to avoid blockage of the sampling pipeline (especially the filter) caused by dust and other pollutants in the sampling gas;

Built in imported air pump (optional).

Application scenarios:

Widely used for online analysis of oxygen content in industries such as protective gas furnaces for high-temperature sintering furnaces such as magnetic materials and brazing furnaces, protective gas furnaces for electronic semiconductors, and glass process requirements.
