Do you understand the difference between gas analyzers and gas detectors
Although there is only a two word difference between gas detectors and gas analysis, there are many differences in actual pronunciation. Gas detectors are gas concentration detection instruments, while analyzers belong to gas analysis instruments, and there are also many types of these two instruments. In order to better distinguish between gas detectors and gas analyzers, today we will introduce the differences between them.
The difference between gas detectors and gas analyzers
1. Differences in instrument structure:
Usually, the structure of a gas detector only includes a detection probe (sensor) and a sensor signal conversion circuit. It is a relatively simple instrument. The interior of the gas analyzer is not only equipped with probes (sensors), but also has a complete gas path system, which can introduce sample gas into the instrument, release the instrument after sampling, or recycle the entire gas path system.
2. Differences in detection methods:
The detection method of a gas detector is to directly detect various gases exposed to the air or sample gas environment through the probe section. The detection method of a gas analyzer is to introduce the measured gas into the instrument through a special method for measurement, and then release it outside the instrument after completing the measurement.
3. Differences in control methods for measurement conditions:
The gas detector does not involve the adjustment and control of the sample gas process technology conditions during use, and it also does not need to consider the environmental conditions of the sample gas during the detection process. It can directly detect the gas. The gas analyzer is equipped with a complete set of gas path systems and external supporting equipment, forming a relatively complete chemical process flow. The gas analyzer can adjust and control the working conditions of the sample gas in all aspects, so that the sensor can achieve normal and stable operation. This is also the main reason why the gas analyzer can accurately obtain measurement data.
