WTW Analyzer TresCon®  analyzer for nitrate/SAC

TresCon® analyzer for the simultaneous determination of nitrate and SAC at 254 nm - reagent-free measuring methods at minimal operating costs

  • Simultaneous measurement of nitrate and SAC (254 nm)
  • UV photometric method
  • 4-beam photometer for highest stability and absolute accuracy

The detection of nitrate is based on an absorption measurement of the waterous sample in the UV range. The SAC (Spectral absorption coefficient) is measured at a wavelength of 254 nm. This sum parameter is a measure for the organic contamination of the water.
