IQ SensorNet CarboVis® Sensors


The CarboVis® is a reagentless, optical-based spectrophotometer built into a rugged, corrosion-resistant field probe for the IQ SensorNet system. The CarboVis can report up to 5 parameters including: COD (total and soluble), BOD, UVT-254, TOC, DOC, SAC (total and soluble) and TSS (optional). The CarboVis probe scans 256 wavelengths per measurement between 200 and 720 nm to provide the most accurate measurements with precise compensation for interferences such as turbidity. The CarboVis provides continuous data to help operational improvement decisions. The probe’s built-in UltraClean ultrasonic cleaning technology reduces routine maintenance requirements.

For Help choosing the right sensor for your application, reference these guides:

  • 5 Questions to Ask When Selecting a UV or UV Vis Sensor Guide
  • UV & UV-Vis Sensor Application Chart.
  • 256 wavelength scans per measurement results in better accuracy and better compensation for interferences
  • UVT-254 measurement used to determine required UV light intensity and contact time for disinfection, lowering a facility’s disinfection costs
  • Factory calibrated
  • 2-year warranty
  • Two options available – one ideal for effluent applications and one ideal for influent/aeration/effluent applications
  • Maintenance free ultrasonic cleaning with UltraClean technology built-in; prevents biofouling from taking place. Built-in air holes for added air cleaning in high fouling applications.

The sensor is part of our IQ SensorNet family of products and works directly with our advanced wastewater process monitoring system. This system is controled by the IQ SensorNet 2020 3G controller or our simplified IQ SensorNet 282/284 controller.
