Background: In reIn recent years, environmental pollution has become more and more serious, bringing great harm. This also reminds us from another aspect to protect the environment and reduce the emission of pollutants. With the globalization of economy and trade, environmental pollution is also increasingly internationalized. The transboundary movement of hazardous wastes is a prominent …
Background: With the continuous development of society, more and more cars are entering the homes of ordinary people. It brings convenience to people, and at the same time, car exhaust has also attracted people’s attention. In particular, the environmental harm caused by nitrogen oxides cannot be ignored. For the treatment of automobile exhaust gas, an …
Background: In May 1968, Naoyoshi Taguchi, the founder of Figaro, was the first to invent the semiconductor gas sensor. Since then, it was not until the 1980s that my country began to develop gas sensors. Although it started late, it has achieved good results. With the development of my country’s electronic component technology and the …

Background: The battery compartment is a compartment where batteries are stored. According to the working principle of lead-acid battery, the positive active material of lead-acid battery is lead dioxide. The negative active material is lead sponge. The electrolyte is a dilute sulfuric acid solution. When charged to 70% to 80%, the positive electrode begins to …

Background: Tap water is domestic and production water that meets certain standards after being disinfected and purified. It is the guarantee necessary for people’s basic daily survival. Disinfection of tap water is directly related to the safety of water, which in turn affects the health and safety of every user. There are many ways to …
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 …

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 …
