Solinst Canada released a new version of the Model 122M Mini Interface Meter, a compact, portable instrument for accurately measuring floating or sinking hydrocarbon/product layers in water (LNAPL and DNAPL).

The Mini Interface Meter comes with a narrow PVDF cable in 80-foot lengths, which fits on a compact reel small enough to fit in a backpack. The cable is accurately laser marked every 1/100-foot, certified traceable to national standards.

The cable is extremely durable, corrosion, chemical and stain-resistant, and easy to decontaminate, which makes it ideal to use when measuring in wells and tanks at refineries, landfills or remediation sites.

The Mini Interface Meters comes with a 5/8-inch-diameter probe that is pressure-proof up to 500 psi. The probe clearly detects when it enters product or water, with an accuracy of 1/200-foot. It uses optical refraction and electrical conductance to determine product and water interfaces.

The circuitry is automatically tested when the meter is powered on. The enhanced electronics only need one easy-to-replace 9V battery to operate. The meters are certified intrinsically safe for use in explosive environments and are ATEX certified.

The Model 122M Mini Interface Meter with narrow polyethylene flat tape is also an option. For deeper applications, Solinst offers the standard Model 122 Interface Meter with laser marked PVDF flat tape in lengths up to 1,000 feet.
