The general requirements for toxic Gas Detectors are relatively strict. If you do not pay attention to any problems when selecting toxic Gas Detectors, it may lead to some accidents. Let's take a look at what problems should be paid attention to in the selection of toxic Gas Detectors!
One: The selection principle of toxic Gas Detector
1. Select the appropriate toxic Gas Detector according to the toxic gas that needs 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. Select the appropriate toxic Gas Detector according to the environment and working conditions of the toxic gas release source and release point
4. Select toxic Gas Detectors with different structures according to the way of laborers' work activities
4.1 Toxic workplaces where workers frequently move should be equipped with fixed toxic Gas Detectors
4.2 Toxic gas workplaces where workers move for a short period of time should be equipped with mobile toxic gas detection
4.3 It is inconvenient to install fixed or mobile toxic Gas Detectors, or in toxic workplaces where workers move temporarily or under emergency conditions for accidents, portable toxic Gas Detectors should be equipped.
Two: The function and quality requirements of the selection of toxic Gas Detectors
1. The Detector should be selective for the detection of toxic gases, be able to resist the interference of non-detected gases, and provide accurate indications and alarms
2. The Detector can cover a certain monitoring area, and the toxic gas released in this area can be effectively detected and alarmed. 3. The Detector can automatically compensate for changes in ambient temperature and humidity, and it can prevent mechanical damage, rain and sandstorms, etc. There are protective measures, and there should be an 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 the 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 relevant standards and specifications
7. Within the specified calibration time interval, all technical indicators of the Detector should meet the requirements.
The above are the problems that toxic Gas Detectors should pay attention to. When detecting toxic gases, you should be fully prepared and follow the selection principles and precautions!
