The Solinst 122 Interface Meter is designed to accurately measure the depth and thickness of non-aqueous phase liquids (NAPL) in groundwater. It detects both light (LNAPL) and dense (DNAPL) hydrocarbon layers in wells and tanks, making it ideal for environmental site assessments and remediation projects.

The robust probe uses an infrared light source and detector system to differentiate between air, water, and hydrocarbons. An audible tone and LED light indicate product or water contact, providing clear, accurate readings. The tape is made of chemical-resistant PVDF with permanent laser markings every millimeter for precise depth measurements. The system is certified intrinsically safe and built to withstand rugged field conditions.

Features:

• Accurately detects both LNAPL and DNAPL layers
