HS-818 ammonia nitrogen monitor

Application field

The principle of HS-818 ammonia nitrogen online monitor is based on the analysis method specified in GB7478. It is automatically controlled by the microcomputer to automatically collect the water sample to the automatic online monitoring instrument for measuring, storing and printing the whole process. It is widely used in the automatic monitoring of ammonia nitrogen content in industrial, domestic sewage and lake surface water, and is also suitable for environmental management work such as total pollutant discharge control.
