How to use toxic gas detector

1 The detector shall be calibrated and tested in time No matter what the instrument is, it shall be checked and calibrated carefully before use, especially for toxic gas detector If the instrument is not calibrated and tested in time before use, the accuracy of the instrument itself may deviate In this case, if the firefighters enter the site of toxic gas leakage, it may cause serious casualties, with unimaginable consequences Therefore, it is necessary to calibrate and test the gas detector in time before using it 2 Pay attention to the concentration measurement range of the detection instrument The toxic gas detector has its fixed detection range Only when the measurement is completed within the measurement range, can the instrument measure accurately If the sensor is out of the measurement range for a long time, it may cause damage to the sensor For example, the toxic gas detector, working in a high concentration of toxic gas environment for a long time, may cause sensor damage Therefore, if the fixed instrument sends out out out out of limit signal, the measuring circuit should be closed immediately to ensure the safety of the sensor 3 Pay attention to the use environment of the detection instrument During the use of the toxic gas detector, pay attention to the prevention of electromagnetic interference If there is electromagnetic interference in the use process, there will also be errors In addition, the temperature, humidity, pressure, wind speed, wind direction, whether there is dust, whether there is corrosiveness, whether there is other gas interference and so on will also affect the detection effect of toxic gas monitor 4 Pay attention to the maintenance of toxic gas detector Don't place or hang articles on the detector The installed gas detector can't move the position of the device at will When purchasing, try to choose the product that can be replaced by the sensor probe, so as to facilitate the later use In the process of using toxic gas detector, we must strictly follow the above points to ensure the safe and reliable operation of the instrument
