UV500
Online UV‑Visible Water Analyzer
The UV500 is an on‑line water analyzer with a high‑resolution 2048‑pixel UV‑visible spectrograph (180–750 nm) enabling simultaneous multi‑parameter monitoring (COD, BOD, TOC, NO₃, PO₄, colour, turbidity, Cr VI). Optional UV‑visible fluorescence for PAH detection, integrated nephelometric turbidity via laser diode, and a xenon flash lamp rated for >10⁹ flashes with automatic acid‑based cleaning ensure reliable, low‑maintenance operation in wastewater treatment, river monitoring, and chemical process control applications.
