What are the functions of VOC gas detectors?
At present, there are various forms of gas detectors in the gas detection industry. Whether it is common or uncommon gases, there are various gas detection tools to detect them. With the continuous development of technology, in order to detect the concentration of VOC gases in the environment, we can use various VOC gas detectors for detection. What are the functions of these VOC gas detectors?
1. Detecting the concentrations of VOCs, VOCs, and TVOC in various environments. In many industries, especially in environmental protection, detailed classification of VOCs is often made. VOCs and TVOC are often seen as a representation of volatile organic compounds in the environment, and these VOC gas detectors can detect them.
2. Although the result detected by the VOC detector is a total VOC concentration, if we know the types of gases contained in the target and the proportions of each gas, we can obtain the concentrations of various gases in the environment.
3. If it is known that the target environment is a single VOC gas, the true concentration value of this gas can be accurately measured. For example, if you know it is benzene, you can input the CF value of benzene to obtain the correct benzene value. However, the results of such tests are not standardized and rigorous enough. We can use a VOC benzene detection tube combined with a VOC detector to accurately detect the benzene concentration.
4. If you have a rough idea of the types of target gases, it can be used as an alarm for entering hazardous areas. For example, fire protection, emergency rescue, sewer survey, and so on. The usual method is to select the alarm threshold of the VOC gas with the lower alarm threshold based on a general knowledge of the type, because in a bad situation, if there is no alarm, then everything is fine.
5. VOC is a general term for organic volatile compounds, such as benzene, toluene, xylene, hydrocarbons, and other organic volatile gases. VOC gas detectors can effectively help us detect them, but if we need to detect a specific gas concentration in the environment, VOC detectors cannot specifically detect it. In this case, we recommend using gas detection tubes for related detection.
