The Geotech Interface Meter is designed to measure the thickness of LNAPL (light non-aqueous phase liquid) layers and water level elevations. The instrument features a HDPE coated steel-core tape clearly marked in 1/100 increments for precise elevation data.
The Geotech 1.5" Float Interface Meter is specifically designed to measure the depth of LNAPL (Light Non-Aqueous Phase Liquid) and DNAPL (Dense Non-Aqueous Phase Liquid) layers in wells and tanks.
