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.

Main feature

1. Continuous automatic analysis of industrial wastewater and ammonia nitrogen in lakes

2, LCD display, continuous record value, real-time printing or manual printing, store at least 1 million data

3, with automatic temperature control system, and the temperature set point is continuously adjustable

4, automatic alarm function, when the ammonia nitrogen exceeds the limit, the instrument fails, can emit sound and light alarm

5, automatic protection when the system balance damage, can automatically cut off the power supply to ensure safety.
