One meter can be used for both photometric and pH measurements. The HI-83325 benchtop photometer measures 8 different plant nutrient water quality parameters using 9 different methods. This photometer features an innovative optical system that uses LEDs, narrow band interference filters, focusing lens and both a silicon photodetector for absorbance measurement and a reference detector to maintain a consistent light source. It ensures accurate and repeatable photometric readings every time. Key parameters are: Ammonia, Calcium, Magnesium, Nitrate, Phosphorus, Potassium, Sulphate and pH.
