Accurate oil/water interface measurement

Solinst 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 mm or 1/100 ft. PVDF is extremely durable, highly chemical-resistant and easy to decontaminate. Tape lengths up to 300 m (1000 ft) are available. The Mini Interface Meter has 25 m (80 ft) of PVDF cable. The 16 mm (5/8") dia. probe is pressure-proof the full length of the tape. The reel electronics are efficient, needing one 9V battery to operate. These interface meters are certified intrinsically safe for use in explosive environments.
