Solinst’s 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.
