A touchscreen oxygen and moisture analyzer for IG applications

Joseph Ha
Product Manager, Purity & Specialty

A next-generation oxygen (O2) and moisture H2O analyzer designed for various industrial gas (IG) applications, the MonoExact DF310E combines trace-level measurement with new performance and operational benefits.

Built around the latest innovations in software and hardware – including a non-depleting Paramagnetic and updated Coulometric digital oxygen sensor – it offers enhanced user control and a reduced cost of ownership.

It also offers plug-and-play capability to operate the AquaXact Al2O3 probe for a dual measurement of oxygen and moisture. When connected to the moisture sensor, the screen is designed to simultaneously display both oxygen and moisture measurements.

Comprehensive analog and digital communication options ensure simple integration into a wide range of systems.

 

The definitive solution for IG gas production and bottling and blending

The MonoExact DF310E has been designed specifically to accurately measure oxygen and moisture in various industrial gas (IG) applications including nitrogen, argon and hydrogen production*‡, tanker transfil, specialty gas blending and electronic gases production. Combining Servomex’s latest advances in sensing technology and analyzer design into an advanced new platform, the DF310E is easy to operate and integrate into a wide range of systems.

* Paramagnetic cell is not for use with flammable samples
‡ Analyzer for use with flammable samples shall be configured with stainless steel inlet and outlet plumbing only

MonoExact DF310E

A no-compromise solution

Offering comprehensive analog and digital communication options for simple integration into a wide range of systems. Includes a Flat Line Alarm that monitors sensor measurements at LDL thresholds. MonoExact DF310E is backward-compatible with existing DF-310E installations, ensuring it complies with existing standards and customer agreements without the need for re-testing or re-qualification.

Simple maintenance and reduced ongoing costs

Built around the latest innovations in sensing technology combined with advance software and hardware – including a non-depleting paramagnetic and digital coulometric oxygen sensor – MonoExact DF310E builds on the original DF-310E with touchscreen operation, features to aid in commissioning and self-diagnostics monitoring benefits that improves user control and reduces cost of ownership. Updating firmware, downloading diagnostic files and copying the analyzer setup to transfer to another unit of identical configuration takes just a few clicks.
