Solinst 122M Mini Interface Meters are designed to measure the depth and thickness of floating (LNAPL) and sinking (DNAPL) non-aqueous phase liquids in groundwater monitoring wells. They are ideal for use in tight spaces and remote locations.

The narrow 5/8" (16 mm) probe is made from durable stainless steel and PTFE, making it resistant to corrosion and chemical degradation. It uses an infrared light and detector system to distinguish between air, water, and hydrocarbons, with an audible tone and LED indicator for clear readings.

The high-quality PVDF flat tape is chemical-resistant and features permanent laser markings every millimeter for precise depth measurement. The tape is flexible and easy to decontaminate, making it suitable for repeated field use.
