HQ-6800 is a highly integrated online monitoring device for nutrients. One instrument can simultaneously monitor four parameters: nitrate, nitrite, ammonia nitrogen, and phosphate. Using wet chemical analysis methods, accurate and stable analysis data can be obtained; HQ-6800 is a water quality analysis device with high flexibility and strong anti-interference ability.
Product Features
1. Small scale design, low energy consumption, low reagent consumption, suitable for integration into small-scale water quality automatic monitoring stations on the shore, greatly saving station construction costs and avoiding complex land acquisition procedures;
2. Adopting classic wet chemical analysis methods, the data is stable and reliable;
3. Adopting MODBUS RS-485 communication method, it can be connected to remote computers to achieve remote monitoring;
4. The human-machine interface is intuitive and friendly, allowing users to view the instrument's operating status, real-time and historical data through the touch screen, and modify machine settings;
5. Multi parameter automatic measurement, any measurement parameter can be selected, and the measurement interval can be set arbitrarily;
6. Manual/automatic calibration, long-term autonomous operation, low maintenance, long maintenance intervals, and low operating costs;
7. Innovatively apply microfluidic analysis technology.
