Potassium Dichromate SpectroPhotoMeter

The potassium dichromate spectrophotometer utilizes the characteristic that potassium dichromate reacts with reducing substances under acidic conditions to produce green trivalent chromium. It determines the chemical oxygen demand by measuring the absorbance at a specific wavelength. This method is used for the quantitative analysis of organic pollutants in water quality testing. During operation, the water sample is digested with reagents and then directly measured.
Selection
When selecting, pay attention to whether the measurement wavelength range includes 600 nm and whether the supporting ready-made reagents are complete. Consider the turbidity interference compensation function for water samples. Check whether the instrument has automatic calibration and temperature control to ensure the stability of the digestion process. Choose a manual or automatic model based on the daily number of samples tested, and verify the detection limit requirements specified by local environmental standards.
