nitrate analyzer / water / benchtop / in-line

The TresCon ON 210/OS 210 are analyzer modules used for online Ammonium, Nitrate/SAC, and Nitrite measurement. These devices use a reagent-free measuring method, equipped with a 4-beam measuring method for optimal background compensation. The devices are also capable of regulation of nitrate degradation in denitrification, and continuous monitoring of nitrate effluent values. They are provided with ions that absorb UV light of certain wavelengths, used for measuring nitrate. This ultra-violet light from a pulsed photoflash lamp passes through a flow-thru measuring cuvette, where it is partially used by the ions in the sample flow. The Spectral Absorption Coefficient (SAC) is measured with a wavelength of 254nm, which represents the organic water pollution. Its resolution (display) is 0.1mg/l for the 0.1 to 100mg/l range.
