The gas detector's shelf life
The gas detector 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, so we also need to separate the life of the instrument Speaking, these two parts are the most important components of the gas detector.
Let's first look at the sensors in the gas detector. The sensors have a fixed service life, and the service life of sensors with different principles is different. For example, the normal design life of the sensor based on the electrochemical principle is two years before it has to be replaced. The replacement time generally has little to do with the number of uses and the storage time, because the electrochemical sensor has an electrolyte inside, which will naturally decrease during the placement of the sensor. Therefore, it will be consumed even if it is not used, so it basically has a fixed replacement cycle, and it must be replaced once it expires, so we recommend that users do not prepare sensor accessories in advance when using the detector, otherwise it is a waste and loss.
The second part is the circuit board part of the gas detector. From this point of view, a circuit with reliable design and sufficient materials can basically guarantee the service life of the fuselage for 3-5 years. Of course, we also refer to normal use, not rough Bad and irregular storage and operation such as operation discarding. Some portable gas detectors have suction pumps and batteries, and these accessories can generally be used for about 2 years.
For the service life of the gas detector, generally speaking, there will be no problems with the circuit board under normal use. In most cases, the failure of the sensor causes the instrument to fail, so the service life of the gas detector is equal to the service life of the sensor. The service life of the electrochemical sensor is about 2 years. After 2 years, it is necessary to test the performance of the instrument and then judge whether to replace the sensor.
