PFAS Accepted Equipment

The Model 122 Oil/Water Interface Meter is designed to measure floating or sinking hydrocarbon layers in water (LNAPL and DNAPL).

The Model 122 P8 16 mm (5/8") narrow pressure-proof probe clearly detects when it enters product or water, with an accuracy of 1 millimeter or 1/200 ft. It is excellent in almost all product monitoring applications.

It uses optical refraction and electrical conductance to determine product and water interfaces. A continuous light and tone indicate a non-conductive product. Water is indicated by intermittent signals.
