Online TOC Analyzer
HydroMetric online organic-load analyzer uses UV254 spectrometric absorption to continuously track soluble organic matter and report TOC together with COD and BOD indicators. The direct-immersion, reagent-free design is intended for wastewater treatment, industrial effluent and surface-water monitoring where fast continuous measurements and low routine maintenance are required.

Applications
Suitable for continuous organic-load monitoring at wastewater-treatment influent and effluent points, industrial wastewater discharge, surface water and other long-term water-quality stations.
Installation & Integration
The immersion sensor eliminates routine sample transport and chemical reagent handling. Automatic optical-window cleaning helps reduce fouling. MODBUS RS485 and analog outputs support integration with PLC, SCADA, data loggers and remote monitoring platforms.
Selection Guidance
Select the optical path/range according to expected organic loading. For an RFQ, provide the target TOC/COD/BOD range, water type, installation point, cable length, available power and required communications so the configuration can be matched to the project.
