NICO

Digital, optical photometric InSitu sensor for nitrate with turbidity compensation
TriOS's new low-cost nitrate meter

Based on the device platform concept of TriOS sensors like OPUS, LISA and VIPER, TriOS introduces NICO: a low-cost UV photometer for the determination of nitrate. The four detection channels enable a pre­cise optical determination of nitrate by absorption, taking into account turbidity and organic substances that pose a problem for many products currently on the market.
An internal temperature correction additionally increases stability of the measured values.
Equipped with our G2 interface with web browser configuration and internal data logger NICO includes features that are much more advanced than those of comparable devices available on the market.
The unified platform of all TriOS photometers also facilitates a standardized spare parts and consumables system, which allows the use of a wide range of accessories for our devices. Furthermore the cutting-edge G2 interface enables quick integration into third-party systems.
