The gas detector is mainly composed of the sensor and the motherboard 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 sensor.

First, Let's take a look at the sensors of gas detectors with fixed working life and different working principles. For example, the electrochemical principle, the normal design life of the sensor to two years to be replaced, the general use of the replacement time and storage time has little relationship. Electrochemical sensors are naturally reduced in the process of placing the sensor with electrolyte, and are not consumed, so there is basically a fixed replacement cycle, which must be replaced in one year, so it is best not to prepare the sensor components in advance when using the sensor, otherwise it is waste and loss.

The second part is the circuit board part of the gas detector. Even if you only look at this point, the generally stable and material-sufficient circuit basically Guaranteed 3-5 years of body life. Some portable gas detectors have suction pumps and batteries, and such accessories can generally be used for about 2 years.

The above description: Under the normal use of the gas detector, there is no problem with the circuit board. Most of the sensor failures cause instrument failures. Therefore, the life of the gas detector is equal to the life of the sensor. The life of the electrochemical sensor is about 2 years. After 2 years, the performance of the instrument should be tested to determine whether to replace the sensor.
