Instrument application:

Widely used in food deep processing enterprises, food and drug supervision bureaus, shopping malls and supermarkets, quality supervision and inspection, industrial and commercial management, catering testing, major food safety monitoring systems, and other units.

Function introduction:

1. The Android intelligent operating system adopts more efficient and user-friendly operation, and the instrument has network cable connection, WiFi networking upload, GPRS wireless remote transmission function, and can quickly upload data.

2. Capable of detecting all detection items in the same software and displaying detection results visually through the same window.

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

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

5. Display method:≥ 7-inch LCD touch screen display, user-friendly Chinese operation interface, intuitive and simple reading.

6. Equipped with a new generation embedded thermal printer, it can be manually printed or automatically printed. After the detection is completed, the detection report and QR code can be automatically printed.

7. The light source adopts imported ultra-high brightness light-emitting diodes, which have high precision, strong stability, controllable light source, and can turn off unused light sources, resulting in lower power consumption.

8. Adopting USB2.0 interface design, it facilitates data storage and movement, and can be directly connected to a computer at any time, and can be used to control instruments. Implement data queries, browsing, analysis, statistics, printing, and more.

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

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

13. 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:
