We have developed a DH-PROTO equipment to measure the Unit-Water Content of concrete. In this paper, using the DH-PROTO and accredited certification HI-330 was to be measured and compared to the Unit-Water Content and evaluating measurement stability. In experimental results by using a capacitive equipment DH-PROTO and HI-330, Estimation error of DH-PROTO and HI-330 according to the type of binder is -4.4 to 2.0%, -7.4 to 4.0%, measuring equipment for Unit-Water Content in concrete showed excellent performance in reliability assessment measures. Also, in the estimation error according to the type of fine aggregate it appeared to 9.1～2.8% and 3.4～10.4 %, respectively, it was judged excellent in performance and accuracy levels. Thus, it expected to be released as a commercial product through further studies.
