Principles to Be Observed When Selecting Toxic Gas Detectors
Toxic gas detectors generally have strict requirements. If you don't pay attention to any issues when selecting a toxic gas detector, it may lead to some accidents. Let's take a look at what issues should be noted when selecting a toxic gas detector!
Principles for selecting toxic gas detectors:
1. Choose a suitable toxic gas detector based on the toxic gases that need to be monitored and alarmed in the workplace.
2. The detection range, detection box alarm accuracy, selectivity, and service life of the toxic gas detector should meet the alarm requirements. The detector should have the ability to resist poisoning and damage
3. Select appropriate toxic gas detectors based on the environment and working conditions of the toxic gas release source and release point. 4. Choose different structural forms of toxic gas detectors according to the worker's work activity mode. 4.1 Fixed toxic gas detectors should be installed in toxic workplaces where workers frequently work
4.2 For toxic gas workplaces where workers engage in short-term activities, mobile toxic gas detectors should be installed. 4.3 For toxic gas workplaces where it is inconvenient to install fixed or mobile toxic gas detectors, or where workers engage in temporary activities or in emergency situations where accidents occur, portable toxic gas detectors should be equipped. The functions and quality requirements for the selection of toxic gas detectors are as follows: 1. The detector should be selective in detecting toxic gases, able to resist interference from non detection gases, and provide accurate indications and alarms. 2. The detector should cover a certain monitoring area, and effective detection and alarm can be achieved for toxic gases released in this area. 3. The detector should have automatic compensation for changes in environmental temperature and humidity, protective measures against mechanical damage, rain, wind and sand, and electromagnetic interference to avoid signal distortion.
4. The detector should have reliability assurance functions such as zero adjustment, calibration, and fault alarm.
5. The alarm mode of the detector should enable workers to respond in a timely manner, and if necessary, it can be linked to the control device.
