‘Aggressive Chemical’

An Engineeringtalk guide

Start with the news release TVOC monitor can be installed without barriers from Ion Science, which we summarised at the time by saying "Ion Science has introduced the ATEX-approved three-wire TVOC monitor for use without safety barriers in Zone 2 hazardous areas.". Several months prior to that, we featured the news release Huntsman expands Probimer 77 solder resist range from Huntsman Advanced Materials: "Probimer 77 White, the latest addition to the Probimer 77 solder resist range, has been introduced by Huntsman Advanced Materials.".

In November 2009, we covered the news from Yokogawa - take a look at Yokogawa pH sensor suits aggressive solutions which says: "The Yokogawa SC24 is a differential combined pH sensor intended for inline process control in applications involving aggressive and dirty solutions: for example, brine in chlorine manufacturing. ".

Take a look also at the news release from Autoclave Engineers, Liquid pumps designed for oil, water and chemicals, as well as Taegutec replaces CT5000 grade with Cermet CT7000 from TaeguTec UK, and Accelerometers obtain hazardous-area certification from Wilcoxon Research.
