Adopting sequential injection fixation ring 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 quantification and quantitative tube quantification, 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.

The device has a simple structure and is easy to maintain. Operators can operate it proficiently after simple training.

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, with proportional coefficients between ranges - fixed, enabling accurate measurement of all ranges with a single calibration range.

High stability and significantly better repeatability than the national standard.
