What should be paid attention to when choosing a toxic and harmful gas detector?
The general requirements for toxic and harmful gas detectors are relatively strict. If you do not pay attention to any problems when selecting toxic and harmful gas detectors, some accidents may occur. Let's take a look at what should be paid attention to when selecting toxic and harmful gas detectors. Question it!
1: Selection principle of toxic and harmful gas detector
1. According to the toxic and harmful gases that need to be monitored and alarmed in the workplace, select the appropriate toxic and harmful gas detector
2. The detection range, detection box alarm accuracy, selectivity and service life of the toxic and harmful gas detector 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 toxic and harmful gas detectors with different structures according to the working activities of workers
4.1 A fixed toxic and harmful gas detector should be set up in the toxic and harmful workplaces where workers often move.
4.2 Toxic and harmful gas workplaces where workers are active for a short period of time should be equipped with mobile toxic and harmful gas detection
4.3 It is inconvenient to install fixed or mobile toxic and harmful gas detectors, or in toxic and harmful workplaces where workers are temporarily active or in emergency conditions, portable toxic and harmful gas detectors should be equipped.
2. Functions and quality requirements for the selection of toxic and harmful gas detectors
1. The detector should be selective in the detection of toxic and harmful gases, resist the interference of non-detecting gases, and provide accurate instructions and alarms
2. The detector can cover a certain monitoring area, and the toxic and harmful gases released in this area can effectively detect and alarm
3. The detector has automatic compensation for changes in ambient temperature and humidity, protection measures against mechanical damage, rain and sandstorms, etc., and anti-electromagnetic interference function to avoid signal distortion.
4. The detector should have reliability guarantee functions such as zero adjustment, calibration and fault alarm
5. The alarm mode of the detector can enable workers to respond in time, and the control device can be linked if necessary
6. The detector should meet the requirements of GB12358: the instruments used in explosion-proof places should meet the requirements of GB50058 and GB3836.1, and other components and transmission wires should meet the requirements of their relevant standards and specifications
7. Within the specified calibration time interval, the technical indicators of the detector should meet the requirements.
The above are the problems that the toxic and harmful gas detector should pay attention to. When detecting toxic and harmful gases, you should be fully prepared and follow the selection principles and precautions!
