X84; Calibration - LaMotte DC1500 Mode D'emploi

„ CALIBRATION

The colorimeter is precalibrated. In order to comply with NPDWR or NPDES reporting regulations,
the calibration should be checked periodically by using a set of reference standards including a
0 mg/L blank and 0.3, 1.0, and 3.5 mg/L chlorine. To prepare these standards, a LaMotte 1000
mg/L standard chlorine equivalent solution (Code 3858) is available. Consult with your local
regulatory agency to determine standardization frequency.
