- J
  James KleinAug 7, 2025
  If you are getting incorrect measured values from your Secomam Measuring Instruments, there could be several reasons. First, check if the cuvette is dirty and clean it. Second, ensure that the dilution is done correctly by making the dilution again. Third, verify that you've selected the appropriate method; if not, select another method. Also, it’s important to ensure that both the zero measurement and the blank value are accurate by performing the zero again and measuring the blank again.
