One instrument can complete the testing of more than 200 food safety indicators. The instrument has reserved expansion ports, allowing for the addition of new testing items in the future. The equipment is suitable for both fixed-point laboratory testing and outdoor mobile sampling, making it ideal for enterprise self-inspection, canteen ingredient acceptance, and on-site sampling inspection by regulatory authorities.

II. Core Product Advantages: Detection Capability: 6 independent detection channels; four-wavelength cold light source at 410, 520, 590, and 630nm, with the ability to expand up to 64 wavelengths for light path switching; different channels can simultaneously run different detection projects; colloidal gold module with track-type automatic transmission scanning and CT line automatic recognition; built-in multi-category sample database, allowing custom entry of sample names and inspection units; built-in national limit standards, with automatic comparison and determination of detection results; automatic accumulation of sample numbers; uninterrupted continuous sample feeding and detection.

The hardware and operating system are primarily controlled by an ARMCortex‑A7, RK3288 quad-core processor with a clock speed of 1.88Ghz; equipped with a 7-inch LCD touch screen and an Android smart operating system; featuring a scanning high-precision optical sensor; intelligent constant current voltage regulation, automatic light source calibration, and no temperature drift during long-term continuous operation; and comes with built-in operation demonstration videos for easy learning by operators.

The new generation of high-speed thermal printer for data output and transmission supports automatic and batch printing of test reports and QR codes; it offers multiple networking options including WIFI, 4G, GPRS, and Ethernet cable, enabling data upload to the food safety supervision platform; it features a standard USB driver-free interface, allowing for U-disk copying and result export to Excel; and it has local storage capacity for 200,000 test records.

Intelligent protection and management features include power-on self-test and zero adjustment, with automatic verification through repeated detection; user name and password permission management to prevent unauthorized personnel from making mistakes; support for modifying determination thresholds and calibration values, with data retention even in the event of power loss; support for instrument calibration, parameter locking, and factory reset; expandable detection items and upgradable firmware; DC12V DC power supply, support for on-board power supply, and optional 6Ah high-capacity lithium battery for outdoor mobile detection.

III. Optional Expansion Features: Optional 6Ah high-capacity lithium battery; firmware upgrade to expand more testing items; complete set of pre-experimental processing consumables; various testing reagent kits (100 tests/kit).

Detailed Application Scenarios Production Side: Raw material warehousing and finished product outgoing self-inspection for food deep processing enterprises; Circulation Side: Ingredient entry screening for supermarkets and farmer's markets; Catering and Campus: Quick acceptance inspection of ingredients for school canteens and enterprise canteens; Regulatory Agencies: On-site supervision and sampling inspection for market supervision and inspection and quarantine departments; Breeding and Slaughtering: Safety screening of meat and aquatic products for breeding farms and slaughterhouses; Scientific Research and Teaching: Teaching experiments in college laboratories.

VI. Overall Appearance and Hardware Description: The handheld protective case is an integrated unit; it integrates a detection chamber, a touch display screen, and a built-in printing module. The body is equipped with USB ports, network communication interfaces, and power supply interfaces. The case is shockproof and pressure-resistant, making it convenient for carrying out sampling outdoors. It can be placed on indoor countertops or outdoor sites.

VII. Brief testing process: Sample sampling → sample pretreatment, reagent color development → instrument testing → automatic calculation and comparison with national standards for determination → print report / export to USB flash drive / upload data to supervision platform. VIII. List of accessories: Carrying case, main unit, power adapter; basic consumables such as cuvettes, centrifuge tubes, scissors; various testing reagents (optional, 100 tests/set).

IX. Brand and After-sales Instructions: Yuntang, a domestic manufacturer specializing in the research, development, and production of food safety rapid testing equipment; Key points for daily maintenance: Regular cleaning of the detection chamber and optical window, regular instrument calibration, and proper storage of reagents away from light; Quality assurance and technical support: Complete machine quality assurance, remote technical guidance, operation training, firmware upgrades, and technical consultation for troubleshooting.

X. Conclusion The YT-G600 multi-functional food safety detector features 6-channel parallel detection, covering over 200 indicators such as food additives, pesticide residues, veterinary drugs, heavy metals, and diseased meat.
