Interference Table
To match the interfering gas symbol with the gas name, reference Table 4, Interfering Gases. Then refer to
Table 5, Cross Interference Table which extends for five pages with each sensor specific gas repeated in each
section of the table, for a column listing of 40 gases. The list is followed by a row of 14 possible interfering
gases per page. Review each page for the applicable sensor gas and then scan across the row for possible
interference gases.
