Use potassium persulfate to digest the sample at high temperature, and all the phosphorus contained in the sample is oxidized into orthophosphate. In acidic media, orthophosphate reacts with ammonium molybdate to generate phosphomolybdate heteropoly acid in the presence of antimony salt, which is immediately reduced by ascorbic acid to generate a blue compound, and the instrument can calculate the concentration of TP in the sample through spectrophotometric conversion.
- Small reagent consumption: The total reagent consumption for a single measurement is less than 3mL, and the maintenance cost is low.
- Separation of toxic waste water and cleaning waste water: Both the amount of toxic waste water and cleaning waste water in a single measurement is less than 15mL.
- Plunger pump quantitative: No contact with reagents, samples, toxic waste water and cleaning waste water, reliable and durable.
- Double optical path detection: Real-time calculation of absorbance, eliminating the interference of the external environment on the optical system.
- Lack of liquid detection and alarm: Automatically identify insufficient sample and reagents supply to avoid no reagent measurement.
- Automatic compensation of turbidity: Automatic compensation based on the turbidity of sample to reduce interference to measurement.
- Automatic range switching: Automatically switch to high-range to measure through dilution if the detection result exceeds the range.
- Key parameter upload: Based on the protocol requirements, key parameters are automatically uploaded to assist in judgment.
- Friendly human-computer interaction: 7-inch color touch screen, the application program is based on the Linux system.
- Support IPv4 network: Compatible with IPv6 network and meet the communication requirements of TCP/IP protocol.
- Support USB and TF card: program upgrade, data export, and data storage can be expanded.
