The number of people die of breathing kitchen smog is even larger than the sum total of people…
As time goes by, the drying up of fossil energy and aggravation of environmental problems are severely restricting the sustainable development of human beings. A new type energy that is clean, safe and efficient has become the new focus of the world. In 1972, Japanese scientists Fujishima and Honda…
CO sensors from SPEC, which are mainly applied in smart buildings and air quality measurement, have obtained UL certification. Through UL independent tests, SPEC’s product 3SP-CO-1000 is confirmed to be compliant with UL2034 and UL2075. Elements with UL certification boost customer’s confidence on using CO sensor 3SP-CO-1000 and other SPEC’s…
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…
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…
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…
