HS-818 Ammonia Nitrogen Monitoring Instrument

application area

The HS-818 ammonia nitrogen online monitoring instrument is based entirely on the analysis method specified in GB7478. Through microcomputer control, it automatically completes the entire process of water sample collection, measurement value display, storage, and printing as an automatic online monitoring instrument. Widely used for automatic monitoring of ammonia nitrogen content in industrial, domestic sewage, and lake surface water, and also suitable for environmental management needs such as total discharge control.

Main features:

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

2. LCD display, continuous recording of numerical values, real-time printing or manual printing, storing at least 1 million data points

3. Equipped with a temperature automatic control system, and the temperature setpoint is continuously adjustable

4. Automatic alarm function, when ammonia nitrogen exceeds the limit and the instrument malfunctions, it can emit sound and light alarms

5. Realize automatic protection when system balance is disrupted, automatically cut off power, and ensure safety.
