Background:

With the continuous development of science and technology, new gas detectors continue to appear to help us solve gas detection problems. The VOC detector is a widely used detector for continuous measurement of toxic and hazardous organic gases in hazardous or industrial environments. Especially suitable for personal safety protection and on-site VOC detection. So where can VOC detectors be used? Let's take a look today.

Humanity has entered a new century, and protecting the ecological environment and promoting sustainable development has become an important issue facing mankind. But when human beings enter the third pollution period marked by "indoor air pollution" after "soot type" and "photochemical aversion type" pollution. When people pay attention to the protection of blue sky and clear water, rivers, lakes and seas, and the control of environmental pollutants such as the atmosphere. However, it ignores an indoor environmental pollution problem that is closely related to people's life and directly involves human health. Therefore, the importance and necessity of indoor environmental monitoring are explained. Improve people's awareness of indoor environment and strengthen the protection of people's health.

Introduction to pollution:

There are three main sources of pollution in the indoor environment: building materials, decorative materials, and household pollutants. People smoke, cook and produce harmful gases from computers, printers, household appliances, etc. Or outdoor pollutants directly into the room. The main pollutants that cause indoor environmental pollution are: formaldehyde, a colorless and soluble irritant gas, mainly from various adhesive sheets, formaldehyde will make people's sense of smell, heart and immune function abnormal. Benzenes, such as benzene, toluene, xylene. Found in paints, glues and wall coatings. Benzene poisoning can cause dizziness, chest tightness, vomiting and other symptoms. Ammonia, Ammonia is a colorless gas with a strong pungent odor, which is corrosive and irritating to the tissues in contact. It can absorb water in tissues, denature tissue proteins, age tissues, and weaken the body's resistance to disease.

Therefore, on the issue of indoor environmental pollution, on the one hand, we must step up the formulation of various indoor environmental quality standards, and on the other hand, we must carry out scientific testing and management to improve people's awareness of indoor environment, prevent and reduce damage caused by construction, decoration and furniture, etc. indoor environmental pollution. Fundamentally change the indoor pollution situation, protect people's health, and promote the development of my country's indoor environmental protection cause. Therefore, many indoor environment detectors play a role, and indoor environment detection and sensors are inseparable.

PID Photoionization Detectors：

PID photoionization probe or pid sensor realizes rapid detection of VOC gas. Waterproof, easy to clean, durable, multi-range selection, accurate measurement. The PID module has high sensitivity and fast response. It can help you alert VOC at the first time and ensure your health. Entering the VOC gas environment, the response speed is less than 3 seconds, and the zero return speed is extremely fast, which can help you detect VOC instantly. Highly protective, easy-to-clean, waterproof breathable membrane effectively protects against particles and moisture. Easy to clean and maintain. Small size, easy installation, can be carried in portable, fixed tube and other appearance sensors. PID sensors (PID optical ion probes) are widely used in VOC detection in factories, mining areas, chemical areas and other environments.

VOC Monitoring system with screen ：

The volatile organic compound online monitoring system (VOC online monitoring) can be used to monitor the fugitive emission of volatile organic compounds in the factory boundary and the park. VOC gas monitoring systems can be used to measure total hydrocarbons, methane, non-methane total hydrocarbons and benzene in ambient air. Toluene, xylene and characteristic pollutant concentrations. The monitoring data can be transmitted to the monitoring center in real time to realize management functions such as pollutant data display, alarm management, and data analysis. At the same time, customized solutions can be provided for various working conditions and customer needs. When the gas measured by the sensor exceeds the set gas value, the sensor turns on the sound and light alarm function.

The equipment is equipped with an air-cooled condenser and an air filter to cool the gas. Filter large particles. Volatile organic compounds can pass through. It can improve the service life of the probe and make the test result more accurate. High measurement accuracy, up to 1mg/m3. Equipped with glass rotameter: 0.5-5l/min measuring range | measure air flow.
