To order a complete set of refill reagents, order as R-3467. To order individual
reagents or test kit components, use the specified code number.
NOTE: Carefully read the instruction manual for the LaMotte Direct
Reading Titrator before performing the titration described below. The
Titrator is calibrated in terms of alkalinity expressed as parts per million
(ppm) calcium carbonate (CaCO
3
). Each minor division on the Titrator
scale equals 4 ppm CaCO
3
.
EPA AC CEPTED PRO CE DURE
To qualify as an EPA accepted test and to achieve greatest accuracy, the
normality of the *Alkalinity Reagent B should be checked periodically.
Standardize *Alkalinity Reagent B by titrating against 0.05N Na
2
CO
3
;
1 mL = 1.00 mg CaCO
3
. Should a variance of greater than 0.3 mL of
*Alkalinity Reagent B occur, discard and order a fresh bottle of
*Alkalinity Reagent B (Code 4493DR-H). A CaCO
3
equivalent
standard of 100 ppm is also available (Code 6199-H). Refer to Standard
