& nbsp; & nbsp; & nbsp; & nbsp; I believe that everyone should understand the construction of natural gas in our country now, so the use of gas detectors is more extensive, so do you know how to use our portable gas detectors It will be safer.

First of all, like the fixed detector, the portable gas detector should also be calibrated at least once every six months, and the portable gas detector should be calibrated at any time. Zero, so as to ensure its accuracy and effectiveness to the greatest extent. In addition, pay attention to the service life of various types of sensors. In general, when using a portable gas detector, the service life of the sensor is the longest, generally reaching two years, while the oxygen sensor has the shortest time, basically only about one year, and the service life of the electrochemical sensor depends on the electrolyte inside. If it is not used for a period of time, it can be sealed at a lower temperature to extend its use time.

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 1 range, the gas detector will lose its effect, can be measured in time, and the result will not be accurate. If this gas detector is used for a long time in a place beyond the measurement range, the sensor may be damaged.

Again, when using a portable gas detector, you must understand and pay attention to the state of the gas that needs to be detected. This requires the use of personnel 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 an environment within a certain range, due to humidity, temperature and other factors, as well as gases outside the detection object, the performance and function of the sensor will also change, which may occur when the object gas is not detected. Sometimes it comes into contact with the detection object, but the alarm still does not respond.
