Cabinet type oxygen analyzer oxygen measuring instrument Instrument features:

lThe use of imported fuel cell sensors has a long service life, fast response time, high detection accuracy, and calibration cycleLong term characteristics;

lAdopting DTThe protective air path effectively protects the sensor and prevents it from being affected by prolonged exposure to airSensor lifespan;

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

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

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

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

lAutomatic blowback function (optional) to prevent dust and other pollutants in the sampling gas from causing damage to the sampling pipeline（Especially pastBlockage of the filter;

lBuilt 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.
