Description: The analysis of uncertainties is conducted, that arise up in the measuring channel of activity of ions at control of the humus state of soils. The estimations of uncertainties ion-selektivnikh electrodes are pointed, electrodes of comparison, strengthener and ADC, the algorithms of calculation are also got standard, total and extended uncertainties of measuring channel of activity of ions.
Keywords:
humic state of soil, measuring channel, model equalization of transformer, ion- selective electrode, standard vagueness, total vagueness, activity of ions, coefficient of selectivity
