The DF-745SG trace moisture analyser from Delta F brings the capabilities of the 700 series to applications requiring the accurate measurement of trace moisture levels in gas mixtures.

The analyser is also suitable for applications within the specialty gas industry.

Manufactured by Delta F, a division of Servomex, the DF-745SG is a process analyser optimised for measuring moisture in a specialty gas stream.

By utilising the latest tuneable diode laser absorption spectroscopy (TDL) technology, the DF-745SG delivers accurate moisture level readings with a performance enhanced by drift-free operation, low maintenance and low calibration advantages.

This combination of high-sensitivity 100ppb low detection limit with a range of 0.1ppm-100ppm means that specialty gas plant owners and operators can utilise the DF-745SG to improve efficiency, increase plant throughput and improve yields.

At the centre of the DF-745SG is application software specifically designed for blending specialty gases involving single gases and mixtures with up to eight components.

With a database of 13 standard background gases, the user can pre-define gas mixture templates for routine blends or define a custom mixture using the front control panel.

Users can also add custom gases to the database using a simple data collection procedure.

The DF-745SG stores detailed 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 analyser’s built-in data screen or downloaded via a USB drive as a Microsoft Excel spreadsheet report.

The DF-745SG is available in a 19in rack mount suitable for a fixed system and is light enough for cart or other mobile applications.

The analyser 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.

The application firmware allows the user to easily configure the system to meet the particular needs of the plant using pre-defined blend templates.

The hardware design allows the user to start the unit up quickly and easily.

The DF-745SG is suitable for a range of specialty gas production applications including monitoring specialty blends for quality control.
