In the presence of alkaline medium (pH = 11.7) and sodium nitroso ferricyanide, ammonia and ammonium ions in the sample react with salicylate and hypochlorite ions to form a blue compound, and the instrument can calculate the concentration of ammonia 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.
