TriOS OPUS spectral UV sensor

Click2Contact

The TriOS OPUS spectral UV sensor is, by analysing the full spectrum, able to deliver readings for nitrate (NO₃-N), nitrite (NO₂-N), organic water ingredients (COD_eq, BOD_eq, DOC_eq, TOC_eq) and SAC254. It can be used in a wide range of fields from municipal water and wastewater to industrial water treatment, river, estuarine or oceanographic research.

The OPUS examines only the UV spectrum, allowing significantly improved resolution in sampling (0.8 nm/pixel) compared with UV-VIS sensors that examine both UV and visual wavelengths (2.2 nm/pixel). For the targeted variables this is critically important as more coarse resolutions may miss the narrow difference between nitrate and nitrite.

The nano-coated hydrophobic lenses of the OPUS help repel build-up and can be replaced if they become damaged over time. As with other TriOS sensors the optical path length can be customised to suit individual applications and even changed (0.3–50 mm) after purchase if the process conditions change.

Available in both stainless steel and titanium bodies, it also supports a wide range of mounting options including inline pipe fitting, flowcell (with chemical or built-in ultrasonic cleaning), single or multisensor floats and unmanned autonomous buoys with solar power and telemetry.

If a local display or transmitter is not required, the TriOS G2 interface allows direct integration of the sensor to existing systems or data loggers via an integrated network (WiFi/LAN) or ModBus interface. Utilising the G2 module, operators can also configure or download from the OPUS via a standard web browser.
