AUTOMATIC TOTAL PHOSPHORUS, NITROGEN ANALYZER (TPN-580/TPN-580R (reduced reagent type) )
High accuracy and stability！
Total Phosphorous-Nitrogen analyzer is a continuous monitoring system that adopts manual analysis method for monitoring total nitrogen and total phosphorous values present in the sample. Total phosphorus and total nitrogen values are measured simultaneously every hour.
(30 minutes heating at 120℃ in the autoclave with potassium peroxodisulfate)
