Working principle
Working principle of portable ammonia nitrogen analyzer TP2112
- The portable ammonia nitrogen analyzer uses the principle of photoelectric colorimetry for measurement. According to the Lambert-Beer law: when a beam of monochromatic parallel light passes through a colored solution, part of the light energy is absorbed by the solution. If the thickness of the liquid layer remains unchanged, the degree of light energy absorbed is proportional to the concentration of the colored substance in the solution.
- The portable ammonia nitrogen analyzer is a laboratory analyzer. It is a precise portable analytical instrument with powerful functions and convenient use. It complies with HJ/T535-2009 “Determination of ammonia nitrogen in water quality” sodium reagent spectrophotometry.

Precautions
1. When the portable ammonia nitrogen analyzer has obvious faults, users should not open it for repair by themselves, please contact the manufacturer in time.
2. When not testing, the portable ammonia nitrogen analyzer should be placed in a dry environment to prevent the instrument from being unstable due to moisture.
3. In order to measure accurately and stably, the portable ammonia nitrogen analyzer should be calibrated periodically to eliminate the influence of electrical drift, optical drift and temperature drift on the instrument.
