SA-9 Spectra Analyzing Sensor

SA-9 is the new generation of immersion spectra analyzing sensor. It uses standardized spectra algorithms by taking the complete 200 to 710 nm absorption spectrum of water into account to determine the nitrogen and carbon compounds. SA-9's spectrum compensation for light absorbing particles and turbidity provides a unique and high sensitivity approach that allows the monitoring of dissolved organic substances without sample pre-treatment. SA-9 gives reliable readings for NO3-N, NO2-N, organic ingredients (CODeq, BODeq, DOCeq, TOCeq), and a number of other parameters. The sensor can be submerged into water by mounting hardware or using flow cell for bypass installation. Measurement path length is from 0.5 to 35 mm. There is a built-in purging nozzle for cleaning the test window by compressed air or pressurized water stream. There is also an optional clamp-on wiper for automatic test window cleaning.
