Ultra High Purity Gases are single gases; such as Oxygen, Hydrogen, Nitrogen, Argon, Helium, Oxygen, Carbon Dioxide and in other Speciality Gases, with a purity of equal or greater than 99.9995% meaning that 0.0005% of the gas is comprised of other gases (impurities). Ultra high purity gases usually cost more than gases of lower purities due to the process involved in making the gases.

Types of Circuit Breakers. Contact Breakers are designed to detect if there is a fault, usually a short circuit, in the electrical cricuits and a building and automatically switch the power off to prevent damage, people being injured or fires starting. Fuses were the first circuit breakers and were used for many years.

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to date. Over a 100 year period, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is …See more on epa.govPublished: 2021/2/4ABB Library Dead Tank Circuit Breakersabb/abblibrary/DownloadCenter/?showresultstab=truecategoryid=9AAC30300082ABB's newest SF6 gas monitor is intended to be used in applications not requiring the full monitoring capability of the existing CBS or CBS Lite.
