Background: Restaurants and fast food restaurants rely on carbon dioxide to produce carbonated beverages. Examples are soda and beer, so both require the use of a CO2 monitor. Pharmaceutical manufacturers use carbon dioxide to eliminate oxygen from packaging. Not only does it maintain a sterile environment, it also protects the product during shipping. It can […]

Background: Natural gas is an important life energy, and the safety of natural gas pipelines is very important. Gas pipelines have the characteristics of long distance and wide distribution. It is mainly laid underground in cities, passing rivers, ravines, railways and highways along the way. The complex terrain limits the operation method of manual inspection.

Background: Since the “Thirteenth Five-Year Plan”, the concentration of ozone pollution in my country has shown a trend of increasing year by year. In 2020, the average number of good days in 337 cities across the country was 87.0%. The excess days with ozone as the primary pollutant accounted for 37.1% of the total excess

At present, there are many methods and means of gas sensor monitoring gas, including electrochemical method, gas chromatography, thermal conductivity method, infrared absorption method, contact combustion method, semiconductor gas sensor detection method, optical fiber method and so on. However, from the scope of application, popularity and practicality of materials, the application of semiconductor gas sensors is

A hydrogen sensor is a device that can detect the presence of hydrogen. Because hydrogen naturally exists in the atmosphere in very small amounts, about 0.00005% of the volume, these sensors are designed to detect quantities that might be considered dangerous. Gas detectors used to monitor hydrogen are most commonly used to detect leaks of this gas

Ozone sensor is a kind of ozone gas composition, concentration and other information into the information can be used by personnel, instruments, computers and other devices. According to the different working principles, ozone sensors have the following types: 1,Ssemiconductor ozone sensor This type of sensor is simple to manufacture and has the advantages of low

Is ammonia harmful to people’s health? First, ammonia is a colorless gas with a strong pungent odor, lighter than air. The gas often comes from concrete admixtures used in building construction and additives and brighteners used in interior decoration materials. Long-term exposure to ammonia, some people may appear skin pigmentation or finger ulcers and other symptoms; After being

Background How long does it take for a gas leak to cause a violent explosion? The answer is 20 minutes. Many people think it takes hours from the moment the gas starts leaking to the moment it meets a spark and explodes, but scientific tests by the fire department have proved that the process takes only
