Features
- Advanced sequential injection platform with reduced number of components, simple structure and easy troubleshooting.
- High-precision and stable injection pump with non-contact liquid quantification design, less water consumption for high-range dilution, and short dilution time.
- Ten-way valve flow path using laser micro-engraving technology, accurately controlling the size and positioning of the grooves, and using sapphire material for the valve core with ultra-high corrosion and wear resistance, long service life, and good stability.
- Integrated quartz digestion/colorimetric unit, not easily contaminated, and with high absorbance resolution.
- Imported cold light source, no preheating required, and with a life span of up to 100,000 hours.
- Innovative process and algorithm effectively eliminate turbidity interference, and the monitoring results are true and reliable.
- Optimized masking agent formula with strong anti-interference ability against impurity ions.
- Liquid reagents do not require low-temperature storage and can be stored at room temperature for more than 30 days.
- Power-off protection design to prevent data loss, and automatic recovery of working status when power is restored.
- Low comprehensive operation and maintenance cost for trace-level reagents and waste liquids.
- Intelligent fault alarm and automatic reset to avoid abnormal rotation of the instrument.
- Automatic verification and judgment function to meet the requirements of new standards.
- Customizable development of special functions and services to ensure user-friendly and humanized operation.
