Product Overview



NHNG-3010 Industrial Ammonia Analyzer


NHNG-3010 type NH3-N Automatic on-line analyzer is developed with completely independent intellectual property rights of ammonia (NH3 - N) automatic monitoring instrument, is the world's only instrument which using advanced flow injection analysis technology to realize ammonia online analysis, and it can automatic monitoring the NH3-N of any water in a long term of unattended.

It can measure the very low and very high concentration of ammonia nitrogen, suitable for laboratory or field rapid on-line analysis of rivers and lakes water, tap water, waste water, high concentration of ammonia nitrogen content in the sewage and various kinds of solution.



1. The most advanced technique of flow injection analysis and the most safe and convenient analysis method.

2. Unique automatic enrichment function, make the instrument has a large measurement range

3. Reagents are non-toxic, just dilute NaOH and containing pH indicator distilled water, which can be easily formulated. The cost of analysis only 0.1 cents for each sample.

4. Unique gas-liquid separator (patented) make sample abandon the cumbersome and expensive former processing device, don't need to clean the equipment, is now the  most simplified instrument in a variety of similar products.

5. Operating costs and maintenance costs are extremely low.

6. Of ammonia nitrogen concentration is greater than 0.2 mg/L samples, can use ordinary distilled water as the solvent of reagent, easy to use.

The working principle of the novel instrument

Peristaltic pump delivery release liquid (loose) NaOH solution for current carrying liquid, turn set according to the number of sample injection valve, formation of NaOH solution and mixed water sample interval, when the mixed zone after the separation of the gas-liquid separator chamber, release samples of ammonia, ammonia gas through a gas liquid separation membrane were receiving liquid (BTB acid-base indicator solution), ammonium ion make the solution pH, color changed from green to blue. Ammonium concentration after accept the liquid to be delivered to the circulation of colorimeter pool, measuring its optical voltage change value, NH3 - N content in the samples can be obtained.
