2. High level of intelligence, the instrument has self checking function: it has startup self checking and zero adjustment functions, and automatic detection of repeatability.

3. Detection channel:≥ 12 detection channels, capable of testing multiple samples simultaneously, each sample controlled by the program to work separately without interfering with each other.

4. Equipped with a new generation embedded thermal printer, it can automatically print detection reports and QR codes after detection is completed.

5. Adopting a standard USB 2.0 interface design, it supports USB storage, without driver insertion and removal, making it convenient for flexible data storage and movement.

6. The instrument comes with a regulatory platform. The detection results can be directly uploaded wirelessly. Realize data query, browsing, analysis, statistics, printing, etc., and can analyze and process data curves and pie charts, detect long-term and short-term dynamics such as food formaldehyde, and achieve problem estimation and warning.

7. The instrument has a menu library of multiple types of samples, allowing for flexible selection of detection samples. Different detection channels can simultaneously detect different sample items.

8. The sample processing is simple and labor-saving, and the overall operation is fast, safe, and convenient.

9. The instrument has its own protection function, which can be set with a username and password to prevent non staff operations.

10. The instrument has functions of recalibration, locking, and factory reset.

Main parameters:

1. The main control chip adopts ARM Cortex-A7, RK3288/4 core processor, with a main frequency of 1.88GHz, which runs faster and has stronger stability.
