Oxygen Transmitters Used To Ensure The Suitability Of Glove Box Atmospheres
Oxygen Transmitters and analyzers are often used as a diagnostic tool to ensure the quality of the inert atmosphere within a glove box. Unlike a storage compartment within a car’s dashboard, however, there is another type of glove box used by industry, government institutions, and university laboratories. This “other” type of glove box (A.K.A. dry […]
Measuring Oxygen for Welding Applications
Not all welding applications require inert shielding gas. However when it does, use of an accurate and reliable trace oxygen analyzer is an essential tool. TIG (Tungsten Inert Gas) welding of titanium requires the use of inert shielding gas, typically either high purity argon or a mix of argon/helium containing under 100 parts per million (PPM) […]
Atmosperic Conditions Affect Weld Quality
Many fabricators experience welding problems at different times of the year. Moisture (H20) is a prime source of hydrogen. At arc temperatures, water breaks down releasing hydrogen atoms that cause porosity in weldments. Shielding gas supplies are controlled to very low moisture content (-70°F dewpoint or lower). Likewise, the atmospheric conditions in a fabricating facility […]
Welding Titanium in Inert Gas Atmospheres
There are many reasons an application might call for titanium due to its exceptional strength-to-weight ratio. In its unalloyed form titanium is as strong as some steels yet 45% lighter. However, the welding of titanium demands a more calculated approach that most other metals. Titanium is also very corrosive resistant and nearly as resilient as […]
P2O5 Phosphorous Pentoxide Moisture Sensor Technology for Moisture Analyzers
The electrolytic moisture sensor used by Systech Illinois employs the well known phosphorus pentoxide principle for accurate determination of trace levels of moisture in inert gas streams. Principle of Operation The method is termed coulometric hygrometry. It is a primary standard and does not need calibration. According to Faradays law of electrolysis the current generated by […]
Aluminium Oxide Moisture Sensor
The aluminium oxide (AL2O3) moisture sensor provides accurate determination of dew point, frost point, ppm, or relative humidity in most industrial gases. The operating principle of the aluminum oxide sensor is that its capacitance varies with the moisture concentration. The sensor is capable of both ppm and dew point measurements in most industrial gas streams. […]
Homage to cross stitching
Likewise, the asymmetrical cut of the rugs breaks with the classic rectangular shape and contributes to a fresh and contemporary aesthetic, which escapes from rigidity to open up to something new. The CANEVAS GEO rug collection, which also includes matching cushions, is available in three colours: Coral, Green and Grey. If desired, the rugs can […]
In Black and White. The perfect match of all times
As far as memory allows us, we visualize the past in this chromatic combination. Newspapers and books, the classic films and its mysterious stars, the family´s old photos or important events covered by the first television reports that have marked recent history. However, this colourless duo is still in force and moves away from old […]
Perfect finnish: Secto Design’s artisanally produced lights
“How many (insert noun of your choice here) does it take to change a lightbulb?” opens the old joke standard. In the case of Secto Design, it’s more of a case of how many woodworkers does it take to craft a quality-first, distinctive Secto lamp? If you were to head up to the town of […]
