Solinst Oil/Water Interface Meters give accurate measurements of product level and thickness in wells and tanks.

Determination of both floating non-aqueous liquids (LNAPL) and sinking non-aqueous liquids (DNAPL) is quick and easy. The factory-sealed probes are pressure proof and tapes are available in a range of lengths up to 1,500 ft. (450 m).

The 5/8" (16 mm) diameter P1 probe allows easy access through tight spaces and into narrow wells, making this the Interface Probe of choice for most applications. The 1.5” (38.1 mm) P2 probe has a glass cylinder covering the optics which is resistant to all chemicals. The extra weight of the P2 probe is useful on longer tape lengths and when DNAPL is being measured.

The Model 122 Interface Meter has been approved by the Canadian Standards Association (CSA) for use in explosive environments. It is suitable for use in hazardous locations Class I, Groups C&D.

The grounding clip is a safety essential when the meter is used in potentially explosive environments. It also helps ensure that the electronics work properly.

Model 122 & 122M are CSA approved for use in hazardous locations Class I, Groups C&D
