laboratory analytical instruments in China.

This instrument uses Nessler's colorimetry to measure ammonia nitrogen in water. The method is simple and sensitive. The principle is that ammonia nitrogen in the form of free ammonia or ammonium ions reacts with sodium reagent to form a yellow-brown complex, and the color of the complex is proportional to the content of ammonia nitrogen.  The instrument is widely used in drinking water, groundwater, surface water, municipal sewage, industrial sewage, environmental monitoring, colleges and universities, scientific research institutions and other fields water measurements.

1. With imported high performance, long life, high brightness light source and high stability optical system, the instrument has higher repeatability and accuracy. 2. With high performance, low power consumption single chip microcomputer and large screen LCD, Chinese menu, easy to operate, intuitive display. 3. The measurement speed is fast, and the result can be obtained in 10 minutes.

4. The records can be saved and data will not lose even when power is cut off. 5. It can store 20 working curves and 500 historical records, and data will not lose even when power is cut off.
