Multi-component gas analyzer

Multi-component gas analyzer

    Multi-component gas analyzer is widely used in online analysis and testing such as medical treatment, oxygen production, and air separation. Multi-component gas analyzer has an original imported fuel cell electrochemical sensor, fast response, high measurement accuracy, long calibration period, weak acid resistance.

Multi-component gas analyzer has a built-in original imported mass flow meter, the flow display is intuitive and convenient, and the service life is long. The three measured media all have temperature compensation function to reduce the influence of ambient temperature on measurement accuracy.The analyzer has two display modes, Chinese and English, which users can switch freely. The sensor has an automatic protection function without manual intervention. 

Multi-component gas analyzer main features:

1.Large-screen touch screen display, single screen displays three kinds of media concentration values, flow values and other related parameters;

2.Historical data storage function, users can query historical data and historical curves locally at any time;

3.The user can choose the altitude module to avoid the influence of atmospheric pressure changes on the measurement accuracy;

4.H2O, CO users can choose not to use the range sensor;

5.Each measuring medium corresponds to one analog and alarm output;

6.Built-in alarm buzzer, redundant alarm points for three media;

7. If the zirconia sensor is not energized, it does not be consumed, has a long life, and is easy to maintain;

8.Imported film capacitive sensor, fast response and high sensitivity;

9.No reference gas is required, and is not affected by the working environment oxygen concentration;

10.Very good selectivity for the gas to be measured.
