三参数（水位，水温和电导率）

三参数地下水自动记录仪。荷兰新推出的CTD-Diver又一次提高了地下记

录仪的标准。外壳采用抗腐的陶瓷材料，极大地提高了产品的可靠性和长期工作的稳定性。内部三个传感器同时测定水位、温度和电导率，并存储于仪器内存中，可随时下载到计算机进行处理。CTD-Diver可以广泛应用于排放监测，垃圾填埋处理监测，以及蓄水层贮存和土地恢复项目，盐化项目，海水侵蚀项目等。

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.
