We have developed a DH-PROTO equipment to measure the Unit-Water Content of concrete. In this paper, using an accredited certification HI-330 and developed DH-PROTO to measure the Unit-Water Content, it was evaluated by comparing the 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, the estimation error according to the type of fine aggregate was appeared to 3.4~10.4 % and 2.8~9.1%, was determined that excellent performance and accuracy levels with it. Thus, it expected to be released as a commercial product through further studies.
