The Heron H.OIL Oil/Water Interface Meter is a specialized instrument designed to accurately measure the thickness of both Light Non-Aqueous Phase Liquids (LNAPLs) and Dense Non-Aqueous Phase Liquids (DNAPLs) within groundwater or other liquid environments.

Featuring advanced optical sensing technology, the H.OIL can detect even the thinnest layers of oil or other non-conductive liquids. Its slim probe design allows for use in narrow wells and monitoring points. The meter's rugged construction and intrinsically safe certification make it suitable for demanding field conditions
