The YSI UVT-254 sensor is a reagentless, optical-based absorption (SAC) and transmittance (UVT) sensor built into a rugged, corrosion-resistant field probe for the IQ SensorNet system. The probe measures UVT-254 and SAC (spectral absorption coefficient - total and soluble) and can provide correlated values for COD, TOC, BOD and DOC. 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 UltraClean® ultrasonic cleaning technology reduces routine maintenance.
For Help choosing the right sensor for your application, reference these guides:
- 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
- 2-year warranty
- 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 UltraClean technology 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.er.
