We can choose the detector that suits us from the following points:
1. Confirm the type and concentration range of the gas to be tested:
The type of gas encountered in each production department is different. When selecting a (xuanze) gas detector, consider all possible occurrences.
1. Most of the methane and other less toxic alkanes are selected. It is undoubtedly the most suitable to choose the LEL test (inspect and test). This is not only because the LEL detector has a simple principle and a wide application, but it also has the characteristics of convenient maintenance and calibration.
2. If there are toxic gases such as carbon monoxide and hydrogen sulfide, it is necessary to select a specific gas detector to ensure the safety of workers.
3, more organic poisonous (Poison) harmful gas, considering its low concentration of people may cause poisoning, such as aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amine), ether, alcohol (chún), lipids, etc. You should choose the photoionization detection (inspection and test) instrument introduced in the previous chapter (xuanze), and never use the LEL detector to deal with it, as this may cause casualties. Portable gas detector detection technology can be used for harmful gas detection, organic voc gas detection, flammable gas detection, single gas detection. The development of accurate early warning and hidden danger detection technology has become more and more widely used in the detection and elimination of accident precursors. Its development direction is miniaturization and automation, in order to achieve long-term monitoring. The development of portable gas detectors allows the leak process to be discovered at an early stage. The occurrence of certain disasters is inevitable. How to effectively suppress and monitor early warnings, how to rationally use high-tech means for accidents, and to effectively control accidents and reduce casualties and property losses are the practical problems that need to be addressed in key production safety technologies. Through the study of the physical and chemical properties of the early accidents, gas detection and monitoring can effectively carry out pre-disaster suppression, so that accidents that may become disasters are controlled in advance, while protecting personal safety. The key to the transition from passive rescue technology to a new generation of active prevention technology is based on intelligent monitoring technology.
If the gas species cover the above types of gases, choosing a compound gas detector may achieve a multiplier effect.
