The WTW NiCaVis is a reagentless, optical-based spectrophotometer built into a rugged, corrosion-resistant field probe for the IQ Sensor Net system. The NiCaVis can report up to 5 parameters including: Nitrate, Nitrite (optional), COD (total and soluble), BOD, UVT-254, TOC, DOC and SAC (total and soluble).
The NiCaVis probe scans 256 wavelengths per measurement to provide the most accurate data with precise compensation for interferences such as turbidity on the UV-VIS probe. The NiCaVis provides continuous data to help with operational improvement decisions. The probe’s built-in UltraClean® ultrasonic cleaning technology reduces routine maintenance requirements.
Reduced maintenance with UltraClean® ultrasonic cleaning technology; prevents biofouling from taking place. Built-in air holes for added air cleaning in high fouling applications.
This short video demonstrates the ultrasonic cleaning when power is added to this sensor and the milky substance is quickly cleaned off. The UltraClean technology is continuously on and built into the sensor to prevent fouling.
