Easily Detect DNAPL and LNAPL Layers with High Accuracy

Solinst Model 122 Interface Meters provide reliable, accurate measurements of floating or sinking product layers in water (LNAPL and DNAPL). 

They use PVDF flat tape, precisely laser marked every 1/100 ft or millimeter. PVDF is extremely durable, highly chemical-resistant and easy to decontaminate. Tape lengths up to 1000 ft. (300 m) are available. The Mini Interface Meter has 80 ft (25 m) of narrow PVDF cable. 

The 5/8" (16 mm) dia. probe is fully submersible. The reel electronics are efficient, needing one 9V battery to operate, and have an automatic shut-off. Interface Meters are certified intrinsically safe for use in explosive environments and are ATEX certified.
