塩分濃度（電気伝導度）水位温度計

In-Situ社が世界で
初めて実現させた
チタン製水位・
電導度計

Aqua TROLL200はチタン製の小型水位・電導度センサーです。 チタンボディーを採用し、海水や腐食性試料でも安定した計測が可能です。最大の特徴は、水温と塩分濃度を実測する事で密度（比重）を計算し水位に反映させることが出来る点であり、河口付近等の塩分濃度が変化する水域でも非常に高精度な水位計測を実現します。超小型（Φ18.3mm、電源・ロガー・センサー内蔵）の形状は、1インチの観測口にも適用が可能であり、計測の幅が広がります。

Aqua TROLL200 is a small water level and conductivity sensor made of titanium. Adopting a titanium body, stable measurement is possible even in seawater and corrosive samples. The biggest feature is that it is possible to calculate the density (specific weight) and reflect it in the water level by measuring the water temperature and salinity, and it realizes very high-precision water level measurement even in waters where salinity changes, such as near the estuary. The ultra-compact shape (with a diameter of 18.3 mm and a built-in power supply, logger, and sensor) can also be applied to 1-inch observations, expanding the range of measurements.
