With the DF-300E family of oxygen analysers from HMA INSTRUMENTATION, end users have access to accurate, sensitive, and rapid oxygen analysis in their applications – with the flexibility to apply this technology across the broadest range. DF-300E analysers 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 such as semiconductor, hydrocarbon processing, chemical, oil and gas, pharmaceuticals, and more.

For over three decades, the heart of Delta-F oxygen analysers from HMA INSTRUMENTATION 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 precisely proportional to the number of oxygen molecules reduced at the cathode. These non-depleting oxygen sensors provide unsurpassed long-term reliability.
