1. By forming a liquid column, the sample required for one test is as low as 0.5ul, and the trace amount is detected, saving precious samples.

2. The detection concentration range is wide, and commonly used samples can be detected without dilution.

3. The machine does not need to be warmed up, it can be detected after starting up, and the single detection time is about 5 seconds, and the detection is fast.

4. Built-in software, easy and fast to operate, software running fast and stable, no delay, provide a stable user experience.

5. Small size, easy to carry, very suitable for field testing.

6. Can record all the data that the user tests, and has screenshot function, convenient for users to export precious data or delete data at any time. More than 10,000 data can be stored.

7. It can be quickly upgraded by U disk, which is convenient for the instrument to update the software.

8. With user management system, multi-user independent detection, independent management of data.

9. High-definition 7-inch display screen, using capacitance touch screen, full touch operation, can sense the touch of laboratory gloves, longer life and better experience.

10. Has power-on self-test function, it can quickly and accurately judge whether there are impurities in the detection platform when the machine is started up.

11. The material of the sample detection platform is stainless steel and quartz optical fiber, high strength and anti-corrosion.

12. With cuvette measurement function, the cuvette measurement provides stirring and heating auxiliary functions at the same time, which makes the cuvette detection more powerful and uses more detection scenarios.(A2-PLUS)

13. Support kinetic detection, kinetic detection provides users with an intuitive absorbance change curve, user-defined wavelength points to view the relationship between absorbance changes over time, and 100 kinetic programs can be built-in.(A2-PLUS)
