PWI Product Water Interface Meters

Meters Detect and Measure LNAPL or DNAPL

Rugged construction means you’ll get lots of use out of these PWI Meters. The electronics tolerate severe scratches and condensation, which reduces the need to replace the prism or the lens. Two separate sensitivity controls for water sensing and fluid sensing circuits give you complete control over the instrument's performance.
Sensitivity control gives you quick readings and prevents false positives of water or hydrocarbons. Choose from 7/16" (No. 125081) or 5/8" (Nos. 125080 & 125082) Probes. Kynar tape is marked in 1/100' or in 1mm graduations for superior accuracy. Built-in hook allows you to support the PWI on the well casing. Requires 9V battery, sold separately. Protect your Meters with a canvas padded Carrying Bag (No. 125084).
