Features of the instrument

  • Advanced sequential injection platform with a significantly reduced number of components, featuring a simple structure for easy troubleshooting.
  • High-precision and stable injection pump with non-contact liquid quantitative design for high-range dilution with minimal water usage and short dilution time.
  • Laser-etched ten-way valve flow path with precise control of groove size and positioning, featuring sapphire valve cores with excellent corrosion and wear resistance for long-term stability.
  • Integrated quartz digestion/colorimetry unit that is not easily contaminated and has high absorbance resolution.
  • Imported cold light source with a lifespan of up to 100,000 hours that requires no preheating.
  • Innovative process and algorithm that effectively eliminates turbidity interference for accurate and reliable monitoring results.
  • Liquid reagents that require no refrigeration and can be stored at room temperature for over 30 days.
  • Low quantitative lower limit suitable for measuring low concentrations of total phosphorus.
  • Power failure protection design that does not lose data and automatically restores the working status upon power restoration.
  • Low comprehensive maintenance costs for trace reagents and waste liquids.
  • Intelligent fault alarm and automatic reset to avoid instrument abnormal operation.
  • Automatic verification and judgment functions to meet new standard requirements.
  • Customizable development of special functions and services to ensure user-friendliness and personalization.
