- The top result is Total Ammonia as Nitrogen
- The next result is Monochloramine as Chlorine
- The next is Free Ammonia as Nitrogen
- The bottom result is the Ratio of Chlorine to Nitrogen

The ratio of Chlorine to Nitrogen is calculated by dividing the Monochloramine as Chlorine result by the Total Ammonia as Nitrogen result. This ratio is always to one as it is defined by how many parts Nitrogen there are to one part Chlorine.

Ex. 1.

In this example the Monochloramine as Chlorine result is 6.162 ppm NH

_{2}Cl-Cl

_{2}and the Total Ammonia as Nitrogen result is 2.546 ppm NH

_{4}-N

The ratio therefore is 6.162/2.546= 2.42:1 displayed as 2.4 N:Cl

_{2}

Ex. 2

In this example the Monochloramine as Chlorine result is 2.468 ppm NH

_{2}Cl-Cl

_{2}and the Total Ammonia as Nitrogen result is 1.094 ppm NH

_{4}-N

The ratio therefore is 2.468/1.094= 2.255:1 displayed as 2.3 N:Cl
