TR-305 Ammonia Nitrogen Total Phosphorus Total Nitrogen Analyzer

Detection Principle:

The TR-305 ammonia nitrogen total phosphorus total nitrogen analyzer from Tongao brand uses Nessler's reagent colorimetric method for ammonia nitrogen determination, closed digestion colorimetric method for total phosphorus determination, and closed digestion ultraviolet photometric absorption method for total nitrogen determination. It uses imported cold light source, narrowband interference technology, and microcomputer automatic data processing to directly display the sample ammonia nitrogen and total nitrogen values. The instrument is widely used in environmental monitoring, sewage treatment, scientific research institutions, and colleges and universities.
