How to choose a toxic gas detector correctly?
The general requirements for toxic gas detectors are relatively strict. If you do not pay attention to any issues when selecting toxic gas detectors, it may lead to some accidents. Let's take a look at what issues should be paid attention to when selecting toxic gas detectors!
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 damage
3. Choose a suitable toxic gas detector based on the environment and working conditions of the toxic gas release source and release point
4. Choose toxic gas detectors with different structural forms based on the way workers work and activities
4.1 Fixed toxic gas detectors should be installed in toxic workplaces where workers frequently engage in activities
4.2 Mobile toxic gas detection should be installed in toxic gas workplaces where workers engage in short-term activities
4.3 Portable toxic gas detectors should be equipped in toxic workplaces where it is inconvenient to install fixed or mobile toxic gas detectors, or where workers engage in temporary activities or under emergency conditions of accidents.
Functional and quality requirements for the selection of toxic gas detectors
1. The detector should have selectivity in detecting toxic gases, be able to resist interference from non detected gases, and provide accurate indications and alarms
2. The detector can cover a certain monitoring area and effectively detect and alarm the toxic gases released in this area The detector should have automatic compensation for changes in environmental temperature and humidity, protective measures against mechanical damage, rain and sandstorms, and should also have anti electromagnetic interference function 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 can enable workers to respond in a timely manner, and if necessary, the control device can be linked
6. The detector should comply with the requirements of GB12358: Instruments used in explosion-proof areas should comply with the requirements of GB50058 and GB3836.1, and other components and transmission wires should comply with 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.
