UV multispectral sensor

TriOS OPUS

The TriOS OPUS sensor is part of the latest generation of UV spectral sensors, designed for online measurements of nitrogen and carbon compounds with a resolution of 0.8 nm/pixel. By analyzing a full spectrum, the OPUS sensor provides reliable measurements of NO3-N, NO2-N, organic compounds (CODeq, BODeq, DOCeq, TOCeq), and a range of other parameters.
Thanks to the TriOS G2 interface, it allows for quick and easy sensor configuration via a web browser. Additionally, through a simple process, it can be seamlessly integrated into existing control systems and external data loggers. With battery operation, it’s portable, and the WiFi connectivity enables control via laptops, tablets, or smartphones without the need for specialized software or apps.
