Manage data while measuring water levels and tide levels of rivers and ports with high precision!
The "HD Sensor Series" is a submersible water level gauge that can be widely used not only in harsh environments such as winter, extreme cold regions, tidal fluctuations, and drought conditions, but also in rivers, estuaries, and ports. It protects the sensor detection part from seawater, barnacles, and other crustaceans, as well as from drought and freezing, using Duracon and a special oil, ensuring stable water level measurements. We offer a high-precision type "HD8300" with a 2-wire system and an accuracy of 0.10% F.S., and a compact pressure detection type "HD8600" using a semiconductor pressure sensor. 【Features】 ■ Reliable design that withstands long-term use ■ Suitable for measurement in any location, including freshwater, brackish water, and seawater ■ Equipped with a high-precision pressure sensor ■ Compact body design ■ Maintains measurement accuracy even in harsh environments ■ Can be installed in drought conditions or environments without water *For more details, please refer to the PDF document or feel free to contact us.
