Delta-F - Trace Oxygen Analyzers

Delta F has been the technology leader in oxygen analysis for years with their unique non-depleting electrochemical sensor technology. Their coulometric sensors eliminated the need for replacing sensors by not depleting over time. The new E-Sensor is Delta F’s revolutionary non-depleting coulometric technology reinvented.

DF-500E Series
Premium performance for the semiconductor (UHP gas) industry.

DF-550E - NanoTrace
DF-560E - NanoTrace II

General Specifications
- LDL: 200 ppt (.2 ppb)
- Resolution: 100 ppt
- Accuracy: 0.5 ppb or 3% of reading
DF-560E
- LDL: 75 ppt (0.75 ppb)
- Resolution: 50 ppt
- Accuracy: 0.1 ppb or 3% of reading

Typical Applications
Semiconductor Fabs
- Bulk gas monitoring & receiving
- Process carts – mobile troubleshooting analyzers
- ASU’s for gas production
Olefin (PE & PP) Manufacturing
- Reactor feed purity

The Series 500 Breathing Air Monitor eliminates the problems caused by inaccurate oxygen readings due to drift or low false readings. It offers:

Reliability - the sensor doesn't decay over time - there are no false low readings
Stability - little or no recalibration over time
Environmental sensitivity - automatically adjusts to minor environmental changes without affecting true oxygen deficiency response
Failsafe operation - battery backup picks up when AC power stops so you will always be safe

Application Notes: Monitoring Oxygen in Glove Box - Oxygen Analysis in the Presence of Acid Gas
