Complete Solution

Pressure sensor with built-in data logger manages and stores pressure, depth to water, water level (stage), temperature measurements as well as conductivity at programmable intervals.

Conductivity measurement

Outputs for conductivity include specific conductivity, salinity, and total dissolved solids.

Accurate

Long-term accuracy: a robust ceramic pressure cell will not deform over time, and an accurate 4-electrode conductivity measuring cell provides outputs for salinity and total dissolved solids (TDS).

High Performance

Mechanical resistance to pressure overload and corrosive waters.

Flexible Installation

Easily installs in wells or pipes of 1 inch diameter or larger with use of convenient adapter plates.
