Green Mon
The GreenMon Oil Content Monitor from Brannstrom is an advanced marine oil-in-water monitoring system designed for highly accurate measurement of oil content in challenging wastewater applications. Utilizing innovative Raman Scattering and Fluorescence Spectroscopy technology, the GreenMon delivers reliable monitoring even in highly turbid and muddy water conditions where conventional oil content monitors may struggle.
Description
Unlike traditional systems, GreenMon analyzes a free-falling sample water jet, eliminating the need for measuring cell windows, brushes, flushing systems, or frequent recalibration. Its robust design minimizes maintenance requirements while providing highly accurate and stable measurements for marine environmental compliance and industrial wastewater monitoring.
