IQ Sensor Net System IQ Sensor Net UV Absorption Sensor for SAC and UVT

Overview Solutions Documentation & Tools


The WTW IQ Sensor Net UV Absorption Sensor for SAC and UVT measures UVT-254 and SAC (spectral absorption coefficient - total and soluble) and can provide correlated values for COD, TOC, BOD and DOC. 

Product Features
  • Reagentless, SAC and UVT sensor built into a rugged, corrosion-resistant field probe for the IQ Sensor Net system
  • 2 wavelength absorption measurement: 254 and a second at 550 nm for turbidity compensation
  • SAC measurement used to determine organic loading without reagents
  • UVT-254 measurement used to determine required UV light intensity and contact time for disinfection, lowering a facility’s disinfection costs
  • Factory calibrated

The probe measures the absorption at two wavelengths: 254 nm and 550 nm to compensate the SAC measurement for interferences from turbidity. 

The probe’s built-in WTW UltraClean® ultrasonic cleaning technology reduces routine maintenance.

The unique cleaning system is completely integrated inside the housing of the sensor without any moving parts. This prevents the risk of penetrating water. Efficient and maintenance-free cleaning over the whole lifetime of the sensor is ensured.

And for applications with extreme fouling, accessorize your sensor with an optional air cleaning. The air flow directed onto the measurement windows reduces the attachment of dirt deposits.

Additional features:

  • Measurement directly in the process, no sample processing, or reagent required
  • Maximum durability due to high-tech materials Titanium/PEEK
  • Maintenance free ultrasonic cleaning with built-in WTW UltraClean technology prevents biofouling from taking place. Built-in air holes for added optional air cleaning in high fouling applications.
  • 2-year warranty

The WTW IQ Sensor Net UV Absorption Sensor for SAC and UVT is ideal for:

  • Control of UV treatment reducing power costs and increasing lamp lifetime
  • Detection of load changes in wastewater treatment plant influent
  • Detection of load changes in wastewater treatment plant effluent
  • Determination of organic loads in rivers and lakes

2 versions:

  • WTW UV 701 IQ SAC - UV IQ sensor for SAC, 1mm (SKU: 481036)
  • WTW UV 705 IQ SAC - UV IQ sensor for SAC, 5mm (SKU: 481038)
