Like the stationary detector, the portable toxic gas detector should also be calibrated at least half a year. And to zero the portable gas detector at any time. In this way, its accuracy and effectiveness can be guaranteed to the greatest extent. In addition, we must pay attention to the service life of various sensors. In general. When using a portable gas detector. The service life of the sensor is the longest. Generally up to two years. The oxygen sensor has the shortest time. Basically only about a year. The service life of electrochemical sensors depends on the electrolyte inside. If not used for a period of time. It can be sealed in a lower temperature place to extend its use time.

Secondly, when using portable gas detection. Be sure to pay attention to its concentration detection range. No matter what kind of gas detector has its own detection range. Beyond this range, the gas detector will lose its effect. Even if it can be measured, the result will not be accurate. If you use this gas detector. Long-term use in places beyond the measurement range. It may cause damage to its sensor.
Again, when using a portable gas detector. To understand and pay attention to the state of the gas that needs to be detected. This requires the user to fully understand the relationship between the gas detector and temperature, humidity, etc. These factors are very important for the correct determination of gas concentration. For example: when it is necessary to detect smoke and dust in the environment within a certain range. Due to factors such as humidity, temperature, and gases other than the detection target, the performance and function of the sensor will also change. It may happen when the object gas is not detected and the alarm situation occurs; sometimes the detection object is touched. But the alarm still did not respond.
Finally, the detection response time of the gas detector is also something that needs serious consideration. During the use of the detector. It is found that the detection value of the display screen will not change after it is stable during the detection. Only in this way can it be used as the last detected data. Also, if the sensor is exposed to high-concentration gas. Due to the adsorption of gas on the pipe wall and other places. It may greatly reduce the effectiveness and reliability of the gas detector.
