Introduction:
Ammonia nitrogen (NH3-N) in the form of free ammonia (NH3) or ammonium salt (NH4+) in water,
the composition ratio of the two depends on the pH value of water. When the pH value is high,
the ratio of free ammonia is higher. On the other hand, the ratio of ammonium salt is high.
Features:
1. Microcomputer, touch type keyboard, LCD LCD, digital clear display, easy to use.
2. The principle of photoelectric colorimetry is adopted, and the convenient reagent is used. After the reagent is added in water sample, the content of ammonia nitrogen can be read.
3. The instrument has a calibration curve in the full range of memory, with power-off protection, and the calibration data will not be lost. Can be manually zero, the data has nonlinear processing and data smoothing function, instrument minimum reading of 0.01mg/L.
