The reference standards are used to check the photometric detection accuracy and reproducibility of measurement results. Adjustment of the photometers is not possible with the reference standard kits. When checking the photometers with the reference standard kit, the appropriate method is selected and the measured value in mg/l is compared with the reference value of the standard kit. The shelf life is two years from the date of manufacture if used and stored properly.
