NG # 02643-HW-KELLER-019
The Keller DCX-22 is an autonomous, battery-powered data logger designed for long-term monitoring of water level (hydrostatic pressure) and temperature. Housed in a stainless steel cylindrical body with a diameter of $22\text{ mm}$ ($0.86\text{''}$), it is specially sized for installation in standard 1-inch (or larger) monitoring wells, boreholes, and piezometers.
