![]() ![]() Pipette, Variable Volume, 1.0 - 5.0 mL (Product # BBP065) Flask, volumetric Class A, Glass, 200 mL (Product #1457445) Chlorine Standard Solution, 50-75 mg/L as Cl 2, pk/16 - 10 mL Voluette Ampules (NIST) (actual concentration on label) (Product # 1426810) The following procedure is one way to accurately prepare 6 chlorine calibration standards from a Hach Chlorine Standard Solution: For example, if using a Hach method that measures from 0 - 2.00 mg/L, prepare calibration standard concentrations that span this range. The calibration standards should span the full concentration range of the test. In order to calibrate the colorimeter, several primary standards (typically 5 to 7) at different concentrations will need to be prepared. However, the instrument does accept a user-prepared calibration curve, if the user chooses to do so. The DR300 for chlorine (Product # LPV40) and the Pocket Colorimeterâ„¢ II, Chlorine (Free and Total) (Product # 5870000) is factory calibrated and does not need to be user calibrated.
