In the chemical industry, safety is the primary prerequisite for production, and as an important tool to ensure the safety of the production environment, the correct selection and use of gas detectors is particularly critical. So how does the chemical industry correctly select and use gas detectors? The following is the sharing of the editor of Zetron Technology.

The following is a detailed answer to how to correctly select and use gas detectors:


I. Correctly select gas detectors


1. Select according to the type of gas to be detected: The key component of the gas detector is the gas sensor, and different sensors can detect different types of gases. Therefore, when selecting, it is necessary to clarify the type of gas to be detected, such as flammable gas, toxic gas, etc., and select the corresponding gas detector.


2. Consider the required functions: Gas detectors have various functions, such as alarm, waterproof, dustproof, explosion-proof, etc. When selecting, the required functions should be determined according to the actual working environment and needs. For example, in places with high explosion-proof requirements, gas detectors with explosion-proof certification should be selected.


3. Choose portable or fixed: Portable gas detectors are easy to carry and can detect gas environments anytime and anywhere; while fixed gas detectors are fixed in a certain area and are used to monitor the gas environment in the area in real time. When choosing, you need to decide based on the detection needs and working environment. 


4. Investigate the manufacturer's production qualifications: Choose regular channels to purchase, and check the manufacturer's production qualifications, market reputation, and product certification.


5. Evaluate sensor performance: The sensor is the core component that determines the accuracy and stability of the gas detector. When purchasing, you should carefully compare the technical indicators of different sensors and give priority to products with better performance.


II. Correct use of gas detectors 


1. Familiar with the instruction manual: Before use, you should carefully read the instruction manual corresponding to the gas detector and familiarize yourself with the performance and operation methods of the machine. 


2. Check the instrument status: Before use, check whether the battery is fully charged to avoid automatic shutdown due to insufficient power during use. At the same time, check whether the air filter at the air inlet is blocked by debris. If there is debris, it needs to be cleaned or replaced. 


3. Perform self-test: When starting the machine, press and hold the start button for three seconds to enter the self-test state. Observe whether the low alarm value and high alarm value set by the detector are accurate. If they do not meet the requirements, they should be calibrated immediately.


4. Calibrate the instrument: After turning on the machine under fresh air conditions, observe whether the initial value is accurate. If the displayed value is inaccurate, it should be calibrated immediately. Calibrate the instrument regularly to ensure its accuracy.


5. Pay attention to the use environment: During use, try to avoid collision with the instrument to prevent abnormal detection data. At the same time, pay attention to waterproofing and impurity input to prevent data abnormality. Do not open the cover at will when adjusting the instrument.


6. Deal with abnormal situations in time: If there are abnormal situations such as the indicator light flashing continuously, the display screen suddenly has no value display, the value displayed in the area where the gas obviously exceeds the standard does not move or the gap is large, the operation should be stopped immediately, evacuated to the air fresh area to observe the problem, and troubleshoot in time. It is strictly forbidden to continue using the instrument before the fault is eliminated.


7. Maintain the instrument: After use, the dust and impurities on the surface of the instrument should be cleaned. When not in use for a long time, the machine should be turned off and stored in a dry, dust-free environment that meets the storage temperature. At the same time, the instrument should be regularly maintained and serviced to extend its service life.


In summary, by following the above recommendations, the accuracy and reliability of the gas detector can be ensured, thereby effectively preventing accidents.
