Пристрій для вимірювання концентрації іонів складових елементів гумусу в ґрунті

Abstract

Device for measurement of concentration of ions of component elements of humus in soil consists of cuvette to which comparison electrode is placed, with output connected top input of first scaling transformer output of which is connected to first input of micro-controller, and ion selective electrode output of which is connected to input of second scaling transformer output of which is connected to second input of microcontroller and output of microcontroller is connected to input of liquid crystal indication device. Additionally third and fourth scaling transformers are included, two multiplexers and two-channel transformer of voltage to frequency.
