- Model M Series UV254 - Wastewater Online Analyzer



Real Tech’s UV254 Online analyzers offer an affordable and accurate solution for real-time UV254 or UVT monitoring. Benefiting from Split-Sense Pro and patented Ortho-beam technology, the need for calibration is limited lowering maintenance requirements. Several path length options provide solutions for wastewater to high purity applications.

  • Real-time UV254 or UVT organics analysis
  • Accurate and reliable data
  • Simple to install and operate
  • Low maintenance, bypass style design
  • 4 line x 20 character backlit LCD display
  • Optional automatic chemical cleaning systems


Dual Feed System
Monitoring two streams is simple and affordable with the dual feed system. The wall mounted cabinet is easy to install with any analyzer, alternating between two streams on timed intervals. The system is invaluable for monitoring organics removal pre and post coagulation as well as pre and post granular activated carbon (GAC) for efficiency measures and optimization.

Real Clean System
The optional Real Clean systems are the ideal choice to keep maintenance to a minimum and performance at its best. The systems can be programmed to meet the cleaning demands of each site, with the option to recycle 90% of the chemical cleaning fluid - further reducing maintenance. Systems can also be equipped with a pumping component for non-pressurized installations.

Custom Calibration
Real Tech’s innovative custom calibration feature allows the online analyzers to be calibrated without DI water or taking the unit offline. A sample is taken from the drain line of the analyzer and tested with a P200 meter or equivalent for UVT. The UVT value is then entered under the Custom Calibration tab in the menu system and the calibration is automatically updated. No further calibration is required.
