TR-109B portable ammonia nitrogen analyzer

Detection principle:

The TR-109B portable ammonia nitrogen analyzer from Tongao brand reacts with Nessler's reagent to form a light yellow brown complex in the form of free ammonia or ammonium ions. The absorbance of the complex is proportional to the ammonia nitrogen content, and it is directly displayed as the ammonia nitrogen content (mg/L) after calculation by a microcomputer chip using colorimetric method.
