UV254 ONLINE ANALYZER M SERIES WATER QUALITY MONITORING SOLUTIONS OVERVIE W Real Tech’s UV254 online analyzer provides rapid real-time measurement of organic matter in water or wastewater. 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. Real Tech’s UV254 M series is cost effective and accurate, making it a practical choice for many applications where alternative organics monitoring solutions would be too costly and complex. MEASUREMENT PRINCIPLE FEATURES & BENEFITS • Practical, accurate and affordable • Real-time UVT or UV254 organics monitoring • atented technology provides superior P measurement performance • Operator friendly, low maintenance design • Wastewater to high purity measurement ranges • Innovative custom calibration feature • Simple to install and easy to operate MUNICIPAL DRINKING WATER MUNICIPAL WASTE WATER INDUSTRIAL PROCESS WATER INDUSTRIAL WASTE WATER The M series UV254 analyzer utilizes light at a 254 nm wavelength as most organic compounds, specifically aromatic organics, absorb light at this wavelength. Benefiting from Real Tech’s patented Ortho-Beam technology and innovative Split-Sense Pro technology, lamp drift and fluctuations are compensated for, providing an accurate and stable output overtime.
