The Solinst Interface Meter Model 122 gives clear and accurate measurements of product level and thickness in wells and tanks.
The Model 122 Interface Meters have been approved for use in explosive environments. They are suitable for use in hazardous locations Class I, Div 1, Groups C&D based on standards of the Canadian Standards Association (CSA).

The  Model 122 Interface Meter with laser marked PVDF tape is now ATEX certified under directive 94/9/EC, as II 3 G Ex ic IIB T4 Gc. The grounding strap is a safety essential when the meter is used in potentially explosive environments. It also ensures that the electronics are properly protected.

Determination of both light (floating) non-aqueous phase liquids (LNAPL) and dense (sinking) non-aqueous phase liquids (DNAPL) is quick and easy. The factory-sealed probes are pressure proof (up to 500 psi.) and tapes are available in a range of lengths from 100 - 1000 ft or 30 - 300 m.

The 122 Interface Meter uses the P8 Probe, which is 5/8" (16 mm) in diameter and stainless steel. It is pressure proof, up to 500 psi. The beam is emitted from within a Hydex cone-shaped tip. The tip is protected by an integral stainless steel shield, and is excellent for the vast majority of product monitoring situations. The circuits are powered by a single standard 9V battery which is housed in an easy-access drawer in the faceplate of the reel.

Features:

• Determination of both light (floating) non-aqueous phase liquids (LNAPL) and dense (sinking) non-aqueous phase liquids (DNAPL)
• Product (Non-conductive liquid) = Steady light and tone
• Water (Conductive liquid) = Intermittent light and tone
• Sensor accuracy to 1/200 ft or 1.0 mm
