DEW CONDENSATION RAINFALL METER AND ENVIRONMENT TESTING MACHINE USING THE DEW CONDENSATION RAINFALL METER

To provide a dew condensation rainfall meter and an environment testing machine using the dew condensation rainfall meter that are able to accurately estimate, with a simple structure, an adhering state of moisture on a sample surface.SOLUTION: A dew condensation rainfall meter includes: a dew condensation meter in which a hydrophilic material is installed on a substrate and an electrode is installed on the hydrophilic material; and a rainfall meter in which a water-repellent material is installed on a substrate and an electrode is installed on the water-repellent material. In an environment in which various samples are exposed outdoors or in an environment in which accelerated environmental conditions (temperature, humidity, sunlight, and the like) are artificially reproduced and a degree of deterioration of each of the samples is evaluated, the dew condensation rainfall meter 1 is installed at substantially the same position as the sample, and an adhering state of moisture on a surface of the dew condensation rainfall meter 1 is detected.SELECTED DRAWING: Figure 1 【課題】簡易的な構造で試料表面の水分の付着状況の予測を精度よく行える結露降雨計および結露降雨計を用いた環境試験機を提供することを課題とする。【解決手段】基板に親水性材料を設置し、親水性材料に電極を設置する結露計と、基板に撥水性材料を設置し、撥水性材料に電極を設置する降雨計とを有する結露降雨計であって、屋外で各種試料が曝される環境下、または、促進的環境条件（温度・湿度・太陽光など）を人工的に再現し試料の劣化度合を評価する環境下で、結露降雨計１を試料と略同一位置に設置し、結露降雨計１の表面の水分の付着状況を検知する。【選択図】図１
