It is a new kind of automatic on-line analyzer used for simultaneously measuring Total phosphorus, total nitrogen and chemical oxygen demand (UV method) in the water. WDet-5000 TPN using the latest photoelectric measuring, UV-vis spectral measurement techniques, has features of accurate meas-urement, high integration, low detection limit, high
eliability, strong adaptability, etc. Instrument reagent can be used on its own in accordance with the relevant national standard.
Full spectrum (200-800nm) measurement techniques, can simultaneously measure ammonia nitrogen and COD(UV method)
With automatic leakage alarm and self-diagnostic function, safety in use, efficient analysis
