Product details
TR-203 Total Phosphorus and Nitrogen Analyzer
Detection Principle:
The TR-203 total phosphorus and total nitrogen analyzer from Tongao brand uses a closed digestion colorimetric method for total phosphorus and a closed digestion ultraviolet photometric absorption method for total nitrogen. With imported cold light source, narrowband interference technology, and microcomputer automatic data processing, it directly displays the COD, ammonia nitrogen, and total phosphorus values of the sample. The instrument is widely used in environmental monitoring, sewage treatment, scientific research institutions, and colleges and universities.
