Do you understand the difference between a gas analyzer and a gas detector?
Although there are only two words between gas detector and gas analysis, there are many differences in actual sound. Gas detector is a gas concentration detection instrument, while analyzer is a gas analysis instrument, and the two instruments There are also many types of gas detectors. In order to facilitate everyone to better distinguish gas detectors and gas analyzers, today I will introduce to you the differences between them.
The difference between gas detector and gas analyzer
1. Differences in instrument structure:
Usually the gas detector structure only includes the detection probe (sensor) and the sensor signal conversion circuit part, which is a relatively simple instrument. The interior of the gas analyzer is not only equipped with a probe (sensor), but also has a complete set of gas circuit system, that is, a complete set of gas circuit system that can introduce sample gas into the instrument, release the instrument or recover it after sampling.
2. Differences in detection methods:
The detection method of the gas detector is to directly detect various gases exposed in the air or in the sample gas environment through the probe part. The detection method of the gas analyzer is to introduce the measured gas into the instrument for measurement through a special method, and then lead it out of the instrument after the measurement is completed.
3. Differences in control methods for measurement conditions:
When the gas detector is used, it does not involve the adjustment and control of the technical conditions of the sample gas. At the same time, it does not need to consider the environmental conditions of the sample gas during the detection process, and can directly detect the gas. A complete set of gas system inside the gas analyzer and external supporting equipment constitute a relatively complete chemical process. The gas analyzer can adjust and control the working conditions of the sample gas in all directions, so that the sensor can work normally and stably. This is also the main reason why gas analyzers can accurately obtain measurement data.
It can be seen that there is a big difference between gas detectors and gas analyzers. You should clarify your own requirements before using it, and then choose the instrument that suits you.
