The Lifetime Of the Gas Analyzer is Mainly Related to the Gas Analyser

The online gas analysis equipment is mainly composed of the sensor and the main board circuit of the device itself. We divide it into two main parts, the first part is the sensor part, and the second part is the main part of the detector.

The gas analyzer working principle is based on electrochemical principles, the normal design life is two years, and it is generally recommended to replace the sensor after two years. Generally speaking, the replacement time has little to do with the storage time. Because the electrochemical sensor contains electrolyte, the sensor will be consumed naturally after leaving the factory, which means it will be consumed even if it is not used. Therefore, there is basically a fixed replacement cycle, and replacement is recommended once it expires.

Therefore, it is recommended that users do not need to prepare accessories such as sensors in advance when using the detector, otherwise it will be waste and loss. The second part is the circuit board of the gas detector. From this point of view, the circuit with reliable design and good materials can basically guarantee the service life of the fuselage for 3-5 years.

To sum up: When the gas detector is in normal use, there will be no problems with the circuit board. In most cases, the failure of the sensor leads to inaccurate detection of the instrument. So the service life of the online gas analyzer is determined by the service life of the sensor.

The service life of electrochemical sensors is generally about 2 years. After 2 years, the performance of the instrument needs to be tested to determine whether the sensor needs to be replaced. Whenever the sensor is replaced, in addition to the necessary inspection of sensor aging, the instrument needs to be calibrated. Using the corresponding standard gas to calibrate the instrument is necessary.

Generally speaking, each sensor corresponds to its specific detection gas. But there is no absolute one-to-one correspondence between any sensor and gas. Therefore, when selecting a gas sensor, it is necessary to understand the interference of other gases on the sensor detection as much as possible to ensure its accurate detection of specific gases.
