enviroFlu
Fluorometer for measurements of PAH (polycyclic aromatic hydrocarbons). Detects oil in water through UV fluorescence.
PAH, oil-in-water using UV fluorescence
enviroFlu HC is the new generation of immersion sensors for measurement of oil-in-water. The used measuring principle of UV fluorescence is much more sensitive than the conventionally used infrared scattering or absorption method. This allows to determine even the slightest traces of PAH’s, for example in drinking water and cooling water condensates.
Application areas include the petrochemical industry, leakage detection in cooling and wastewater streams as well as environmental monitoring. The devices enable both stationary use in shafts, flows or piping, and mobile use through an optional hand-held measuring instrument. An innovative coating reduces fouling of the optical measuring window and minimizes the maintenance.
