2.2 Interference Data
UniTox™ Model 200 series electrochemical sensors
are subject to interference from other gases. This
interaction is shown in the in the table in Table 4
Appendix A
Interference Table
as the relation between the amount of the interfering gas applied to the sensor, and the corresponding reading
that will occur. All measurements are in ppm unless otherwise noted.
The table is laid out with the Gas type of each UniTox™ sensor in a column on the left side of the page. The
interfering gases are listed in a row across the top of the page. Each page lists all Model Numbers but 5 pages
are necessary to list all interfering gases, thus each page is a repeat of the full line of Detcon UniTox™
sensors. Be sure to reference each page to ascertain the full listing of interfering gases for a particular
UniTox™ sensor.
In example: The first listing shows that the C2H30 Acetyldehyde sensor will have an interference reading of
340 ppm if 40 ppm of C2H2 (Acetylene) is applied.
NOTE: Interference factors may differ from sensor to sensor and with lifetime. It is not
