The Datalogger type 570-II artesian will be fastened by screwing the top piece into the artesian head of the groundwater well. The top piece which has a 1-inch connection thread is water- and pressure-tight. The water level is measured by a pressure sensor according to the relative pressure method, the barometric pressure fluctuation is automatically compensated. The interface for PC- connection of the top piece is protected against unauthorized opening, environmental influences and vandalism.
This Datalogger 570-II is especially suitable for water level and temperature measurements in artesian groundwater production and monitoring wells. The type 570-LTC version can measure the water level and the temperature as well as the electrical conductivity.The very robust construction made of high-quality stainless steel, precise sensor technology and not least the solid HT Datalogger technology guarantees the long-term monitoring success.

The Artesian Well Head is screwed on the connection thread directly on top of the groundwater observation well. The integrated ventilation unit ensures safe closing with rising water level and ventilation of the observation well at decreasing water level to avoid the creation of negative pressure or compressible air pockets. In addition, a lockable opening is provided for check measurements by a Water Level Meter or optionally with connection piece for the installation of a manometer. The Artesian Well Head with an HT well cap is securely closed.
Available sizes: 4 inch/ 4½ inch / 5 inch / 6 inch
