Objects of research - model solutions and natural waters. Methods - three wave photometry. Main results: a prototype device designed to determine the concentration of nitrates, which includes housing with established within the module with a source of UV radiation, cell and sensor. Emitter module is equipped with three UV LEDs and photodetectors as device includes photodiodes. Irradiation of the analyzed water samples and measuring its absorbance is carried out simultaneously with three rays waves following lengths: 265, 310, 345 nm. Obtained satisfactory metrological characteristics of the device on the basis of determining the concentration of nitrates in model solutions and natural waters. Field of use: enviroment protection.
