The general requirements for toxic and harmful gas detectors are relatively strict. If the toxic and harmful gas detectors are selected and do not pay attention to any problems, it may lead to some accidents. Let's take a look at the selection of toxic and harmful gas detectors. The problem! Selection principle of toxic and harmful gas detector 1. According to the toxic and harmful gas that needs to be monitored and alarmed in the workplace, select the appropriate toxic and harmful gas detector 2. Detection range of toxic and harmful gas detector, alarm accuracy, selectivity and use of the detection box Life expectancy should meet the alarm requirements.
The detector should have the ability to resist poisoning damage. 3. Select the appropriate toxic and harmful gas detector according to the environment and working conditions of the toxic and harmful gas release source and release point. 4. Select the toxic and harmful gases of different structures according to the working mode of the workers. Detector 4.1 toxic and harmful workplaces where workers often move, it is advisable to set up a fixed toxic and harmful gas detector 4.2 Workers' toxic and harmful gas workplaces for short-term activities, it is advisable to set up mobile toxic and harmful gas detection 4.3 Inconvenient to install fixed or mobile A toxic and harmful gas detector.
The function and quality requirements of the toxic and harmful gas detector 1. The detector should be selective for the detection of toxic and harmful gases, can resist the interference of non-detected gases, and provide accurate indication and alarm. 2. The detector can cover certain monitoring. Area, the toxic and harmful gases released in this area can realize effective detection and alarm. 3. The detector should automatically compensate for changes in ambient temperature and humidity, and have protective measures against mechanical damage, rain and sand, etc. The electromagnetic interference function avoids signal distortion.
