The main application area of the non-combustible gas sulfur hexafluoride (SF6) is the insulation of high voltage switchgear, transformer and cable. Although sulfur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times that of carbon dioxide (GWP =23,900). In addition, sulfur hexafluoride is odorless, heavier than air, and can accumulate in […]

Sensors in Carbon Monoxide Detectors The electrochemical carbon monoxide sensor uses gel to detect CO. The electrochemical gas sensor is mainly used to detect oxygen and toxic gases. They measure chemical reactions within the sensor to produce a current output proportional to the level of CO. Essentially, Electrochemical carbon monoxide sensor is small fuel cells

We became concerned about gas leakage after we found that some gases had harmful effects on human health. A portable gas detector can be used to monitor gas concentrations around the person, either hand-held or worn on clothing or on a belt/suspenders. These gas detectors are usually battery powered. Alarms and flashing lights appear when

Infrared (IR) gas detection method is based on the absorption of infrared radiation of a specific wavelength through a given amount of gas. Usually two infrared light sources and an infrared detector measure the intensity of two different wavelengths, one at the absorption wavelength and one outside the absorption wavelength. If the gas gets between

CO2 sensor is a kind of gas sensor used to measure the concentration of carbon dioxide gas in atmospheric environment. It is measured in “parts per million” (ppm), usually around 400ppm. Carbon dioxide, a colorless, odorless gas, has long been considered one of the main “greenhouse” gases affecting Earth’s atmosphere. This gas, along with methane,

What is a semiconductor gas sensor? At present, gas sensor plays an important role in environmental monitoring. There are many methods and methods of gas sensor monitoring, including: electrochemical method, gas chromatography, heat conduction method, infrared absorption method, contact combustion method, semiconductor gas sensor detection method, optical fiber method, etc. However, from the application range,

Gas detector is a very important security equipment in any chemical plant. It can provide information on any small leak in any pipeline, and with early action, we can save any production safety incident in the plant. In any chemical plant generally we use four types gas detectors: 1、Hydrocarbon Detecto 2、CO detector 3、NH3 detector 4、Chlorine

There are two main types of weather sensors related to rain and snow. One is a rain gauge used to measure the amount of rain, and the other is a rain and snow sensor used to monitor whether it is raining or snowing. When browsing related materials, I found that there are many articles about

If your job involves crude oil, natural gas, or bacterial decomposition, you are likely to come into regular contact with hydrogen sulfide (H2S) gas. Hydrogen sulfide is a colorless, highly toxic gas that can cause a variety of dangerous conditions. Without proper testing systems in place, the safety of your workers and equipment could be

Whether you’ve just moved into a new home or have been living in your current home for a while, a gas leak detector is a must for security. While they all work in different ways, depending on what gases are being tested, the instrument should be able to detect the presence of combustible or toxic
