三參數(shù)（水位，水溫和電導率）

三參數(shù)地下水自動記錄儀。荷蘭推出的CTD-Diver又一次提高了地下記

錄儀的標準。外殼采用*抗腐的陶瓷材料，極大地提高了產(chǎn)品的可靠性和長期工作的穩(wěn)定性。內(nèi)部三個傳感器同時測定水位、溫度和電導率，并存儲于儀器內(nèi)存中，可隨時下載到計算機進行處理。CTD-Diver可以廣泛應用于排放監(jiān)測，垃圾填埋處理監(jiān)測，以及蓄水層貯存和土地恢復項目，鹽化項目，海水侵蝕項目等。

CTD-Diver

3 Parameters in 1 Housing

Where there is a need to monitor groundwater levels ａnd saltwater intrusion, injected wastewater, or contamination from chemical discharges and landfill sites, the CTD-Diver with its rugged, corrosion proof ceramic housing, is the instrument of choice.

The CTD-Diver is equipped with a four-electrode conductivity sensor that measures electrical conductivity from 0 to 120 mS/cm. There are two options for measuring conductivity: true or specific conductivity at 25 °C. Additionally, pressure and temperature are measured and recorded.
