Chlorine Standards for Model 1200

For use with the 1200 series of chlorine colorimeters. Secondary standards provide a fast way to check calibration without the burden of making primary standards.

Based on Standard Methods for the Examination of Water and Wastewater, 20th ed., 1998, the operator can calibrate a colorimeter using a permanganate primary standard or a chlorine primary standard. Once the meter is calibrated using the primary standard, the operator can insert secondary standards periodically to evaluate the calibration of the instrument.

  • Secondary standard kit contains a blank and 3 standards for low, mid-range, and high chlorine calibrations.
  • Packaged in a small plastic case with Certificate of Analysis stating range of each standard.
