9. 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.

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

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

12. High sensitivity, high detection accuracy, high repeatability accuracy, scanning type high-precision optical sensor.

13. Equipped with a powerful database, you can directly select information such as sample name, testing indicators, and testing unit on the instrument. You can also directly edit and input information such as sample name, testing indicators, and testing unit on the instrument and save it in the sample database.

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

15. Supports USB storage. The result judgment line can be modified, the calibration value of the reference value can be saved, and data will not be lost when power is turned off.

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.

2. DC 12V power supply, can be connected to car power supply, can be equipped with a 6Ah large capacity rechargeable lithium battery, convenient for outdoor flow testing.
