What is the difference between a gas detector and a gas analyzer?

In the words "What is the difference between a gas detector and a gas analyzer?" For this reason, Anhui Xinmu Automation will introduce to our customers in detail what is the difference between a gas analyzer and a gas detector.

Under normal circumstances, gas analyzers are more powerful than gas detectors. Gas analyzers can monitor and analyze gas composition and concentration in real time. For example, zirconia oxygen analyzers can analyze the concentration and composition of oxygen; while gas detectors usually only Can detect the concentration of a single gas.

   Generally speaking, there are six main differences between gas detectors and gas analyzers, as shown below:

   1. The structure of the instrument is different.

  2, the detection method is different.

   3. The control method of the measurement conditions is different.

  4. The operation method to complete the whole process of measurement is different.
