Specifications

It can monitor and measure Ammonia Nitrogen concentration of rivers and lakes, surface water, water supply, sewage treatment plant in industrial and mineral enterprises.

 

1.It adopts touch screen display and Chinese operation interface for easy use.

2.It is equipped with automatic constant temperature controlling system and it can keep the measured solution at the right temperature.

3.It has automatic cleaning, calibration, measurement, recording and storage function. It also has power failure protection.

4.Each functional parameter can be adjusted according to different requirements. In addition, the sampling period of sampling pump can be set at random.

5.It has isolated output signal (420)mA DC, and it has the upper limit and lower limit of corresponding concentration of Ammonia and Nitrogen.

6.The upper and lower limit warning system can be adjusted.

7.It has RS-232 or RS-485 communication port.
