The Difference Between Gas Analyzer and Gas Detector | EXTENT NEWS

Different construction A gas detector has structures that are simple, consisting only of the sensor and sensor conversion circuit. But a gas analyzer not only has sensors indoors, but also has a complete set of pneumatic system, which introduces the sample gas to the instrument firstly then sparks or retrieves the gas.

Different detection methods The gas detector completes the detection by exposing the sensor in the gas or sample gas straight, while the gas analyzer introduces the detected gas or sample gas to the instrument for testing firstly at a distinctive way and then discharges the gas.

Different control methods for detection conditions The gas detector does not possess the alteration and control part of sample gas technical conditions, nor it considers the ecological conditions of the sample gas, but finds directly.

The complete set of electrical system built from the gas analyzer and the outside supporting gear form a complete chemical process, inner part of the gas analyzer adjusts and controls the functioning conditions of sample gas , in order to guarantee the sensors to operate normally and stably. And that is also the assurance that the gas analyzer can get accurate data.

Different surgery methods in completing the Entire detection process On employing the gas detector, the data can be obtained only by putting the instrument in the gas. However, the sample gas must be introduced into the instrument carefully when using the gas analyzer, then rigorous alteration of technological conditions can be manufactured, for example temperature, pressure, flow.

Different Techniques to exclude interference factors in detection The gas detector works by exposing the sensor in air right, it does not have to consider the interference factors in structural design and actual application. Moreover, it can not be designed to exclude various interference factors. However, the gas analyzer shall fully consider various external and internal factors influencing the detection in its design and application, and all the factors must be excluded carefully to ensure the accuracy and credibility of the detection data. Otherwise, it is not allowed or unacceptable for detection to dismiss an influential factor.

Different data accuracy The gas detector only provides qualitative analysis results and rough quantitative analysis data, the data revealed by this instrument can’t stand out and error analysis can not be carried out (because”error” is only applicable when the analysis data deviates from the true value slightly), and so the data can’t be used as an accurate analysis data to determine the improvement and alteration measures of important process. On the other hand, the gas analyzer is a strict measuring instrument providing quite accurate data in quantitative analysis, and the data may used as the basis for improvement of gas production and security production, to guide the production management, quality management and enterprise management. Additionally, such data may be utilized as a significant basis for judicial identification and may be utilized in litigation to ascertain the correct or wrong bounds.
