The proposed device for determining the state of a concrete structure in sulfuric-acid environment contains a measuring electrode, a reference electrode, a measuring transducer, a liquid-crystal display, and a control panel. Each electrode contains a cast plastic casing with a contact tip, active substance, and a current lead. As the active substance, antimony oxide is used. The contact tip of the reference electrode is designed as a tube with a wick. The length of the tube is less than the length of the electrode. The electrodes are connected with the corresponding terminals of the measuring transducer.
