UV254 (UVA / UVT)
PI UV254Sense UVA/UVT from UK provides real time organic UVA (ultra-violet absorbance) and UVT (ultra-violet transmission) analysis monitoring. The concentration of contaminants such as the organics that lead to disinfection by products (DBPs) can be determined by measuring the light absorbed by a water sample at a particular wavelength (254nm). The absorbance of light used in UV254 monitors provides an indication of the amount of aromatic (or reactive) organic matter in water, making it an excellent choice as a surrogate measurement for total organic carbon (TOC) in monitoring organics removal from a process.

UV254 analysers from Pi allow for the detection of natural organic matter (NOM) which is found in all waters and has a bias towards aromatic compounds which provides significant benefit for monitoring DBP formation potential.
