Three points to consider when purchasing a gas detector
In recent years, workers have been stunned by poisonous gas due to the construction of the inspection well, and accidents such as children throwing firecrackers into the well and being injured have occurred frequently. Because the canal under the inspection manhole cover is a sealed site, toxic and harmful gases are easy to accumulate in the well, such as: methane (biogas) , hydrogen sulfide, ammonia and other flammable gases, these gases are prone to combustion and explosion when they encounter open flames and air. At this time, it is necessary to use a gas detector to detect these toxic and harmful gases. So what should consumers consider when purchasing a gas detector?
1. Equipment type selection:
For on-site measurement needs, choose a suitable gas detector. For routine operations, you can choose a portable gas detector for patrol measurement. For closed places that are not convenient for personnel to enter, you need to install a fixed online gas detector to achieve real-time online monitoring.
2. Range selection:
Different gases have different ranges. As the core component of the gas detector, the gas sensor, when the gas concentration at the detection point exceeds the range, the gas sensor will be damaged. Therefore, it is necessary to select a gas detector that matches the range according to the site environment.
3. Gas sensor service life
The gas sensor is the core component of the gas detector, so the service life of the gas sensor is also very important. When the gas sensor exceeds the service life, the measurement data will be inaccurate. Therefore, it is necessary to regularly calibrate the gas detector and the sensor replace.
