DESCRIPTION
The UVM5000 provides online continuous organics monitoring utilizing a 254 nm
ultraviolet light source. The amount of light absorbed provides an ongoing
indication of natural organic matter (NOM) in a flowing sample, and serves as a
continuous surrogate measurement for total organic carbon (TOC). More
specifically, UV254 is the best detector of aromatic or reactive organics which
when combined with chlorine, can form disinfection by-products (DBPs). The
patent pending Ortho-Beam technology provides many significant advantages
while maintaining affordability. The monitor’s unique ability to automatically detect
and compensate for UV lamp fluctuations and quartz fouling minimizes losses in
accuracy over time, and significantly reduces maintenance.
