Delta F Series

Delta F Series Oxygen Analyzers

 

With the DF-300E family of oxygen analyzers, you have access to accurate, sensitive and rapid oxygen analysis in your application—with the flexibility to apply this technology across the broadest range of applications. DF-300E analyzers are used in everything from harsh and hazardous petrochemical processes to glove box applications. The DF-300E family has the flexibility to meet the needs of industries that include semiconductor, hydrocarbon processing, chemical, oil and gas, pharmaceuticals, and more.

 

For more than three decades, the heart of Delta-F oxygen analyzers has been a unique, coulometric sensor—the ultimate in sensitivity. This 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. These nondepleting oxygen sensors provide unsurpassed long term reliability.
