TRANSPARENCY DEGREE MEASURING GUAGE AND TRANSPARENCY GUAGE USING THE SAME

PROBLEM TO BE SOLVED: To solve a problem that, in a conventional transparency gauge, a discrimination of a cross line on a sign plate is subtle, and various troublesome problems occur when confirming by repeated actions, and moreover, the device is not appropriate as the gauge employed simply by a beginner and an ordinary people such as a Juvenile student.SOLUTION: A transparency degree is measured by transparency degree measurement gauges integrated vertically each other by a measurement scale marked with a line measure which is marked upward with a top surface of a sign board as a zero starting point. The transparency degree measurement gauge is inserted into the test water placed in the container and performs the measurement by vertically lifting upward and downward. In this manner, the transparency degree can be repeatedly, simply, and accurately confirmed. Further, a dislocation of the sign board can be prevented, and the measurement of the transparency degree can be greatly improved and simplified by eliminating a need of the adjustment of the zero starting point such as a water surface height at the time of the measurement together with portability of the measurement device.SELECTED DRAWING: Figure 1 【課題】 従来の透視度計では、標識板上の十字線の判別が非常に微妙で、繰り返し動作によって確認しようとすると種々の煩わしい問題が生じていた。さらに、多人数による繰り返し測定においても児童生徒等の初心者や一般人が野外で簡便に使う器具としては適切ではなかった。【解決手段】 標識板の上面を０起点として上方に向けて計測目盛を印した計測目盛尺に係止部材によって互いに垂直に一体化した透視度計測治具によって透視度を計測するものである。容器に入れた検水へ透視度計測治具を挿入し、それを上下させて計測するものである。これにより、透視度を繰り返し簡単確実に確定できること、標識板の排出を防止でき、計測時の水面高さや０起点の調整が不要であるなど、測定器具の携帯性と併せて透視度の計測を飛躍的に改善簡便化することができる。【選択図】図１
