PURPOSE: An apparatus for measuring relative humidity in a concrete having moisture condensation prevention function is provided to prevent error generation in measuring the relative humidity due to moisture condensation, and to measure the relative humidity in the concrete accurately. CONSTITUTION: An apparatus for measuring relative humidity in a concrete having moisture condensation prevention function includes a sensor part (100) and a moisture condensation prevention member (300). The sensor part measures relative moisture by changing electrical characteristics of an electrode when the sensor part is exposed to water molecule. The humidity condensation prevention member comprises a main body (303) and a moisture-permeable and water-proof fiber (301). The main body is installed to surround the outside of the sensor part, and comprises a through-hole connected to the outside. The moisture condensation prevention member passes water molecules through the through-hole so that the water molecules are flowed into the inside, but is installed not to pass the water through the through-hole by blocking the through-hole. |
