Description

This paper describes the development and testing of a single-use multi-sensor system for measuring the concentrations of ions used in nutrition for crops. The sensor consists of a conductive paste material on an insulating PET film; selective ligands can simultaneously measure the concentration of many nutrient ions. It includes electrodes, a heater, a calibration fluid and a waste container, and gives test results within 3 minutes. By using two kinds of sensor systems, pH and EC are measured, together with the concentrations of K+, Ca2+, Mg2+, H2PO4−, NO3− and NH4+. This single-use multi-sensor system is reliable, fast, and easy and inexpensive to use. The single-use multi-sensor system and reference analyzers showed a good correlation for a wide variety of nutrient components.<br>
