IQ SensorNet Optical UV Absorption Probe

The YSI UVT-254 sensor is a rugged, optical-based absorption probe measuring UVT-254 and SAC, ideal for efficient wastewater monitoring.

The YSI UVT-254 sensor is a state-of-the-art optical absorption probe designed for the IQ SensorNet system. IQ SensorNet Optical UV Absorption Probe provides accurate measurements of UV transmittance (UVT) and spectral absorption coefficient (SAC) without the need for reagents. It’s built into a rugged, corrosion-resistant field probe, making it ideal for harsh wastewater environments.

Advanced Measurement

The sensor measures UVT-254 and SAC at two wavelengths: 254 nm and 550 nm. This dual-wavelength approach compensates for turbidity, ensuring precise measurements. The SAC measurement helps determine organic loading, while the UVT-254 measurement aids in calculating the required UV light intensity and contact time for disinfection, ultimately reducing disinfection costs.

Durability and Maintenance

Constructed from high-tech materials like Titanium and PEEK, the YSI UVT-254 sensor is built to last. It features the UltraClean® ultrasonic cleaning technology that prevents biofouling, significantly reducing maintenance needs. Additionally, built-in air holes facilitate air cleaning in high-fouling applications.

Integration and Compatibility

This sensor integrates seamlessly with the IQ SensorNet family, working directly with the advanced IQ SensorNet 2020 3G controller or the simplified IQ SensorNet 282/284 controller. It also includes integrated lightning protection and supports multiple languages, including English and German.
