1. The gas detector is selected according to the field working conditions. The types of gas detectors are different under different working conditions. Some industrial sites propose to use fixed gas detectors, which can be assembled on fixed detection points. Its advantage is that it can monitor the concentration of field gas online 24 hours.
2. During assembly, the position and height of the fixed instrument shall be selected according to the characteristics of the gas to achieve better detection effect. Portable gas detectors are widely used in various industrial and mining enterprises, environmental management and health departments. In an open working environment, the wearable diffuse toxic gas alarm can be selected.
3. If it is in the workplace, it is necessary to detect the enclosed space in the external space before the personnel enter. At this time, it is necessary to use the pump type portable gas detector for detection. Portable toxic gas detector is small, portable, easy to operate, portable and easy to use.
4. To determine the type and concentration range of the gas to be detected, the gas formed in each link of the industrial production process is different, and the appropriate gas detector should be selected according to the actual situation. For example, if there are carbon monoxide and hydrogen sulfide in the field conditions, it is necessary to select toxic gas alarms to detect carbon monoxide and hydrogen sulfide.
