SOLUTIONS FOR OXYGEN ANALYSIS
O 2
Oxygen ( O 2 ) concentration is an essential measurement throughout the Air Separation Unit ( ASU ) process . O 2 forms approximately 21 % of atmospheric air , so is often found as an impurity in nitrogen and argon streams . In addition , O 2 gas product quality is another critical measurement for ASUs , and our Paramagnetic sensor confirms this measurement for both medical and industrial applications .
SERVOPRO MultiExact 4100
SERVOPRO MonoExact DF310E
A high-performance multi-gas analyzer , the SERVOPRO MultiExact 4100 provides up to four simultaneous gas stream measurements , including O 2 , carbon dioxide ( CO 2 ), carbon monoxide ( CO ), nitrous oxide ( N 2 O ), methane ( CH 4 ), and moisture , making it an ideal workhorse analyzer for any ASU gas analysis systems .
For O 2 measurements , it can be configured with Paramagnetic or Zirconia sensing technology , which are both proven , non-depleting digital sensors offering accuracy and precision , especially at the low and high concentrations required for ASUs .
Paramagnetic sensing takes advantage of the magnetic property of O 2 , which has a higher affinity within a magnetic field . It delivers fast , accurate , and sensitive measurements of O 2 at percentage levels .
The Zirconia sensor utilizes a cell made of yttriumstabilized ceramic zirconium oxide , and measures oxygen at ppm levels , ideal for detecting O 2 as an impurity .

Designed specifically for use in industrial gas applications , the SERVOPRO MonoExact DF310E is a digital analyzer that combines accurate trace-level measurement for O 2 as an impurity within Ar and N 2 . It ' s packed with features including an icon-driven guided user interface ( GUI ), advanced digital communications and downloadable diagnostics , which allow almost all service issues to be diagnosed remotely .
The Coulometric sensor is a highly sensitive , capable method of detecting ppb-level oxygen , with an excellent range . It ’ s also very useful for applications which are prone to upset , as ranges span from 100 to 10,000 ppm .
If higher ranges are required , the MonoExact DF310E can be configured with a Paramagnetic sensor , for percentage O 2 measurements between 0-25 %.
The MonoExact DF310E also offers plug-and-play operation for the AquaXact 1688 moisture probe , allowing a dual measurement of O 2 and H 2 O , two of the main impurity monitoring requirements within ASU plants .
