FIELD: measurement technology. SUBSTANCE: invention refers to nondestructive inspection of objects and can be used to measure parameters of process of metal corrosion in conductive liquid media to diagnose condition of technological equipment and pipe-lines. Meter incorporates sensor-probe, unit of preliminary signal processing, multichannel analog-to-digital converter, microprocessor, energy-independent storage module, liquid-crystal display, keyboard, real time clock, heating element and temperature-sensitive element. Meter case housing functional units and elements is placed in sealed protective box. Energy-independent storage module is detachable and can be connected to meter from outside of case. EFFECT: widened functional potential of meter, expanded temperature range in which meter can operate. 4 cl, 3 dwg
