1. Small reagent consumption: the total reagent consumption of single measurement is less than 2mL, low maintenance cost.
2. Separation of waste liquid and waste water: the amount of waste liquid is less than 10mL and the amount of waste water is less than 15mL in a single measurement.
3. Plunger pump dosing: no contact with reagents, samples, waste liquid and waste water, reliable and durable.
4. Dual optical path detection: real-time calculation of absorbance, eliminating the external environment on the optical system interference.
5. Shortage of liquid detection alarm: automatically identify water samples with insufficient reagent supply to avoid measurement without reagents.
6. Support USB, TF card: program upgrade, data reading is convenient, data storage can be expanded.
7. Key parameter uploading: Based on the protocol requirements, key parameters are automatically uploaded to assist judgment.
8. Support IPv4 network: compatible with IPv6 network, meet the TCP/IP protocol communication requirements.
9.7-inch color touch screen, the application is based on Linux open source system.
