Adopting sequential injection quantitative loop technology, the structure is simple, the failure rate is low, the use of reagents is minimal, and the operating cost is low.
The quantitative system is stable and reliable, superior to conventional photoelectric fixed disks and quantitative tubes, and will not decay during long-term operation.
The automatic alarm for instrument failure and automatic recovery after power outage overcome the disadvantages of short service life and high failure rate of similar products.
Humanized design, easy operation, all functions of the instrument are completed through a friendly human-machine interface on the touch screen.
The instrument calibration, parameter recording, and analysis time can be set through remote control.
Strong universality, a universal platform for all chemical instruments, facilitating the stocking of spare parts in the later stage and shortening maintenance cycles.
● Easy to customize; The proportional coefficient between ranges is constant, achieving accurate measurement of all ranges by calibrating a single range.
High stability and significantly better repeatability than the national standard.
