Combines the advantages of three ionomers (three independent potentiometric channels), conductometer, oximeter and thermometer. Combining the capabilities of several electrochemical analysis techniques, gives almost complete picture of the composition and quality of the solution.
Measured parameters
• ions activity (pX);
• molar (М) ions concentration (mol /l);
• mass (С) ions concentration (mg/l);
• Electromotive force (EMF) of electrode systems (mV);
• redox potential Eh (mV);
• specific electrical conductivity (mS/cm);
• total mineralization in NaCl and other electrolytes equivalent (g/l);
• oxygen concentration (%, mg/dm3);
• aquatic environment temperature (°C).
