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

Solar radiation sensors are also known as prominence meters. As photometers, these devices are used to measure broad-band solar irradiance as well as solar radiation flux density, which means they can measure the power of light and heat from the sun. When placed on a flat surface, a prominence meter can be used to identify

A portable gas detector is an instrument that can be carried to the field to detect gas concentrations and give alarm, and is amongst a variety of trusted safety essentials found on board any sea-going vessel. Toxic gases that can be life-threatening are often present on all kinds of vessels, so it is essential to

There have been gas detectors for as long as people have known how dangerous some gases can be in confined space. Canaries were used at the beginning of mining, long before electronic sensors were improved. They are kept underground and excavators are warned if they stop singing or die. We’ve made some amazing progress since
