Product overview Ultra High Purity High stability coulometric trace measurements When you work in quality control of electronic gases, you need an ultra-trace O2 contaminant detector and/or, a gas line leak detection analyzer. The DF-550E can deliver both with high performance, stable measurements in a light and flexible configuration. You need analysis that is both stable, reliable and ultra-sensitive; it needs to deliver consistent results - untroubled by changing sample and flow rate conditions - and be able to overcome upset events quickly and effectively. Flexibility is key and the ability...
