2. The instrument detection module is standardized and intelligent, and the detection items can be freely combined. The detection box is equipped with multiple standard detection units, and the detection module can be adjusted and configured.

3. Display screen: The instrument adopts a 10.1-inch vertical LCD touch screen display, paired with the Android intelligent operating system. The main control chip adopts ARM Cortex-A7, RK3288/4 core processor, with a main frequency of 1.88GHz, which is easy to operate and has stronger performance.

4. Detection channel: ≥ 12 channels; Adopting a precision rotating colorimetric cell design, using the same chip and light source to calibrate accuracy, solving the error values between different light sources, making it more accurate and efficient. (0.1% error between channels 1-12, patent number: ZL2022821055.2)

5. Instrument light source: high-precision imported four wavelength cold light source, each channel is equipped with 410, 520, 590, and 630nm wavelength light sources, and is equipped with advanced optical path switching devices as standard. The patented optical path switching function can achieve 64 wavelengths, and all detection items can achieve simultaneous detection of all channels.

6. The device can be calibrated with one click, automatically saving calibration data, automatically comparing and verifying to obtain accurate light sources. It uses Android SP to store data, and the light source data is never lost, making it convenient for every use.

7. Communication interface: Equipped with wireless communication module, 4G (APN) communication module, Bluetooth transmission, and dual USB interface and RJ45 network cable interface, it can achieve data storage and transmission in multiple ways.

8. Storage method: Supports USB storage, standard USB interface, and driver free installation. The storage capacity of the test results is over 200000, which can generate Excel spreadsheets for copying and has login protection function.

9. Intelligent operating system:

9.1 Operating System: The instrument can automatically correspond to relevant detection channels on the same detection interface, selecting 1-12 sample names at once, without the need to exit the interface, saving operation time. And each channel attribute and sample information can be edited separately, such as the inspection unit, personnel, testing personnel, etc. When printing, check the print display.

9.2. Data integration system: The device homepage automatically summarizes and analyzes testing data, including weekly and monthly testing data, the total number of all tests, including the total number of tests, qualified and unqualified numbers, as well as relevant column analysis charts. All testing data is clear at a glance, without the need for computer queries, making it faster and more intuitive.

9.3. Database system: More than ten database classification management instruments: including project type, project data, testing data, historical records, national standard information, curve information, sampling information, testing information, inspection information, review information, chart information, light source calibration information, print style information, sample library information, etc. The databases coordinate and interact with each other to ensure the authenticity and integrity of the data. At the same time, the product database and historical detection records support one click retrieval function.

9.4. Limit determination system: With a limit inquiry and compliance determination system for added substances. After detecting the results, the system automatically calls the relevant national standards in the system database for comparison and judgment, objectively displaying whether the judgment results are qualified.

9.5 Project preset system: The instrument has a task preset module, which can be preset in advance with one click to provide a convenient and fast new testing plan. Each task can be set with different samples, batches, numbers, sources, remarks, sampling information, testing information, inspection information, re audit information, and more. When sending samples for inspection, one click retrieval and storage information can be accessed multiple times, greatly improving detection efficiency.

9.6. Data supervision system: Synchronized with the supervision platform, data can be uploaded on local area networks and the internet, and test results can be directly transmitted to the food safety supervision platform. Conduct regional food safety supervision, big data analysis and processing, and data statistics, detect the long-term and short-term dynamics of regional food safety, and achieve food safety problem estimation and warning.

9.7.1 New Printing System: Equipped with a new built-in printer and a new custom printing method, it can flexibly check and control as needed: printing of QR code, sampling information, testing information, inspection information, review information, sampling date, testing date, and other information.

9.7.2 A4 paper version report printing function (optional): The device has two display methods for results, which can automatically generate A4 printing templates and small ticket printing templates. External printers can be linked through WiFi and network cables for printing.

10. Power supply mode: The instrument is used for both AC and DC, with a DC 12V power supply. It can be connected to a car power supply and can be equipped with a 6Ah large capacity rechargeable lithium battery. The power level can be displayed in real-time, making it convenient for outdoor flow testing.

11. The instrument has remote upgrade function, which can be targeted and updated by customers. It automatically updates after startup and sustainably updates the system version for free, eliminating the need for traditional products to be updated at the factory, saving time and labor costs and avoiding logistics transportation
