Features of the instrument
- Advanced sequential injection platform, greatly reduces the number of components, with a simple and easy-to-diagnose structure.
- High-precision and stable injection pump, non-contact liquid quantitative design, high dilution range with less water consumption and short dilution time.
- The ten-way valve flow path adopts laser micro-engraving technology to precisely control the size and positioning of the grooves. The valve core is made of sapphire material with ultra-high corrosion and wear resistance, long service life, and good stability.
- Integrated digestion/colorimetry unit with high absorbance resolution.
- Liquid reagents do not require low-temperature storage and can be stored at room temperature for more than 30 days.
- Power-off protection design, no data loss, and automatic recovery of working status when power is restored.
- Intelligent fault alarm and automatic reset to avoid abnormal rotation of the instrument.
- Micro reflux digestion technology and innovative automatic direct wind speed cooling device improve digestion and cooling efficiency and shorten sample processing time.
- Automatic verification and judgment function to meet the requirements of new standards.
- Customizable development of special functions and services to ensure ease of use and user-friendliness.
