Heron Interface Probe
Water Quality - Water Level Meters


Spectra Product#: WQM-000

The Heron Oil/Water Interface meter is used to measure the interface level between two liquids in the same tank, vessel, well or aquifer. The dissimilar density of two liquids means the lower density, non-conductive product will float on top of the higher density, conductive liquid (water). Denser products will tend to sink, creating a layer under the water.
