Delta F DF-745SG

The DF-745SG Trace Moisture Analyzer brings the extraordinary capabilities of the DF-700 Series analyzers to applications in the specialty gas industry as well as allied applications requiring the accurate measurement of trace moisture levels in gas mixtures. This combination of high sensitivity-100ppb LDL-with broad range -100ppm- at an attractive price means that high-value specialty gas operations can now be controlled to ensure high yields economically with a DF-745SG analyzer.

The DF-745SG is a sophisticated process analyzer that has application software specifically designed for blending specialty gases involving single gases and mixtures with up to eight components drawn from a database of 13 standard background gases. The user can pre-define gas mixture templates for routine blends (with up to 30 templates) or define a custom mixture using the front control panel. The analyzer allows the user to add custom gases to the database using a simple data collection procedure. The analyzer collects production data that identifies the components and volumes in a mixture as well as the date, time and moisture content of the blend. This data can be displayed on the analyzer’s data screen or downloaded onto a USB drive and printed out as a report in an Excel format.

The DF 745SG is a versatile tool for help in minimizing the moisture in your specialty gas stream. The analyzer is designed for 19 inch rack mount as a fixed system and, at only 64 lbs, is ideal for cart or other mobile applications. The analyzer can be quickly moved from port to port thanks to isolation hardware and software routines that virtually eliminate long dry down times often associated with these applications.

Based on the same proven design tradition as Delta F's oxygen and moisture instruments the DF-745SG expands the range of applications that can now afford this capable technology.
