UviTec UV254 Analyzer

The UviTec UV254 / UVT analyzer provides rapid real-time measurement of organic matter in water or wastewater output as UV254 (cm-1) or UV transmittance / UVT (%). The UV254 analyzer utilizes light at a 254 nm wavelength as most organic compounds, specifically aromatic organics, absorb light at this wavelength. Benefiting from our innovative Ortho-Beam and Split-Sense Pro technologies, accurate and reliable measurements are output for the highest level of confidence in organics monitoring.

Continuous organic monitoring can bring significant value to many applications including UV disinfection performance and efficiency, coagulation dose optimization, DBP formation potential, source water monitoring and so much more.
