DF-300E Delta F Series Oxygen Analyzer/Sensor
The DF-300E family of oxygen analyzers provides access to accurate, sensitive and rapid oxygen analysis and flexibility across the broadest range of applications. For more than three decades, the heart of Delta-F oxygen analyzers has been a unique, coulometric sensor - the ultimate in sensitivity.
This long term reliable sensor uses a non-depleting, ambient temperature oxygen reaction to produce a current flow that is precisely proportional to the number of oxygen molecules reduced at the cathode.
Features and Benefits
• Oxygen analysis flexibility for multiple industries including
semiconductor, hydrocarbon processing, chemical, oil and gas,
pharmaceuticals, and more
• The performance and flexibility to meet a wide range
of application requirements
• Fast response so you ran react to problems immediately
• Rapid upset recovery response
• Compact and modular design to fit into your plant and process easily
• Affordability you need to justify implementation
• An inert cathode immune to damage from trace levels of acid
and hydrocarbons
• A non-depleting anode so there's no drifting over time, no false low
readings and no frequent recalibrations
• Acid tolerance - the optional STAB-EL™ system removes acids and ionic
impurities from the electrolyte
Performance enhancements include
• Improved purge-down time
• Improved upset recovery
• Elimination of the need for Quick Start
• Improved speed of response
• Extended range of operationl/low end resolution
• Improved linearity and accuracy
• Improved baseline stability
• Improved temperature stability
• 25% improvement in hardiness/acid gas tolerance
• Please note this product is not available in the U.S.

• Temperature: 0 to 150°F (-17.8 to 66°C)
• Flow from 1.0 to 3.0 SCFH
• Pressure: 0.2 to 1.0 psig pressure, vent to atmosphere
Gas Sample Requirements
• 7.75 in X 8.5 in X 10 in (197 mm X 216 mm X 254 mm) (for DF-130E and DF-150E)
• 14 in X 13.18 in X 11.42 in
(356 mm X 335 mm 290 mm) (for DF-140E)

How does it work?
The DF-130E is designed to provide reliable, dependable and accurate measurements at an economic price. You just take it out of the shipping container and start monitoring. Depending on the application, the ultrastable sensor can operate for years without recalibration. The only maintenance requirement is the occasional addition of replenishment solution and an alarm is included.
