  • Illustrating the Dew Point: An effective way to determine

    Jul 18, 2017Figure 1: The National Roof Contractors Association (NRCA) map. Image courtesy Professional Roofing. According to NRCA, dew point calculations are necessary whenever the outside average January temperature is below 4 C (40 F), and when the expected interior winter RH is

  • Kozy Insulators - A+ Corporation

    Daytime and nighttime temperature cycling can cause erratic gas analysis due to adsorption/desorption effects. Low ambient temperatures can cool a sample below its dew point, causing condensation. Condensed liquid can result in unstable pressure regulation or regulator “freeze up”, inaccurate sample analysis, and analyzer damage.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.
