Potentiometer facilities of ions activity measurement of humus elements in soil

Abstract

Three new schemes of realization of potentiometer facilities intended for measuring of activity of ions are suggested, their transformation equations are given, characteristics of digitization errors change are investigated. On the basis of reference information about the errors of component elements used for construction of the offered facilities of measuring and errors of digitization the total errors of measuring facilities are calculated and recommendation concerning the possible ways of increasing the reliability of ions activity control of component elements of humus in the soil are given.
