02-Nitrite Concentration

Read the test strip. Is the nitrite concentration acceptable? (Minimum 1200ppm) If not, use Pencool 3000 to adjust the SCA Concentration. The chart below may be useful.

(Note: nitrite is used to estimate the overall SCA concentration because it depletes from the system prior to all other protective additives. Therefore, if the nitrite level is maintained, all other elements of the SCA will
be properly maintained.)
