LaMotte LTC3000wi Turbidity & Chlorine Lab Meter - Manual (Page 72)

 COLOR
CALIBRATION
Color Standards
The meter has been calibrated with colored standards of known
concentrations of platinum cobalt. One unit of color is equivalent
to the color that is produced by 1 mg platinum/L in the form of the
chloroplatinate ion. A 500 cu Color Standard (60 mL, Code 6058-H) is
available from LaMotte.
Calibration Procedure
The meter should be calibrated with platinum cobalt color standards.
For the most accurate results, a user calibration should be performed
with LaMotte Color Standards. The calibration should be done with
a distilled or deionized water blank and one color standard of known
concentration. The concentration of the calibration standard should be
similar to the expected concentration of samples that will be tested.
