With the development of petrochemical industry, the categories and applications of inflammable, explosive and toxic gases are also increasing. Once leakage of these gases occurs during production, transport or using, it will cause poisoning, fire or even explosive accident, which will severely prejudice the safety of people’s health and possession….
Instead of PM2.5, O3 has become the “culprit” of air pollution in summer. Therefore, NOx, as an important component to generate ozone, draws the attention of environmental experts. How can nitrogen oxide influence the environment? And how can them be controlled to reduce ozone pollution? Environmental Protection Agency in Chengdu…
Volatile Organic Compounds (VOCs) are carbon-based chemicals that evaporate at room temperature. The term “VOC” may refer to a single compound or collectively to all such compounds. Scientific Definition Variations Different organizations define VOCs based on specific regulatory needs: ASTM d3960-98: Organic compounds participating in atmospheric photochemical reactions. US EPA: Carbon…
In recent years, gas alarms are more or less used in office spaces, smart homes and factories. As fuel of natural gas and coal gas, methane is widely applied for civil or industrial use. A methane alarm is to measure the concentration of methane gas and make alarm when it…
A sensor technical seminar between ISweek and SST was successfully held on July 16th, 2018 in Zhongke Mansion. Paddy Shannon, the technical director of SST, and Sports Chen, the Manager of ISWeek, attended this seminar, in which the technology of fluorescent oxygen sensors was mainly introduced. The seminar started with…
This application is to measure the air pollution made by automobile exhaust, mainly the concentration of CO, in underground parking garages. According to practical demands or specific requirements of ventilation, the sensors measure air pollution index to control mechanical ventilation in an automatic energy saving manner. The number of sensors…
With the concept of smart home being popular and awareness of household safety being enhanced in recent years, the usage rate of gas alarm is increasing. Also, actions with alarm is becoming more efficient because of the combination of gas alarm and the control of smart home, making it more…
With 40 years of application and development, gas sensors and alarms have been successfully improved. For now the gas alarms can be warranted to operate 5 years without maintenance. It has become a standard manner to enhance the durability and to prevent false alarm with a built-in filter. All Figaro…
With ambient temperature going down, the air-conditioners in vehicles are used by an increasing amount of people, some of which even fall into sleep in the care. This is very dangerous, for that every year there are deadly accidents nationwide due to sleeping in a car with the air-conditioning on….
As an important part of space environment simulator, vacuum system plays a pivotal role of simulating the vacuum background in space during the thermal tests of spacecrafts. It is usually divided in to two types: rough pump and high vacuum. Any abnormality of vacuum degree in thermal tests will not…
