Grain heavy metal detector

Against the backdrop of increasingly strict dual supervision of food security and food safety, food and agricultural products are highly susceptible to heavy metal pollution (such as cadmium, lead, mercury, arsenic, etc.) during cultivation, storage, processing, and distribution, and may be accompanied by multiple risk factors such as fungal toxins, pesticide residues, and antibiotics. These pollutants have the characteristics of strong concealment, persistent toxicity, and easy accumulation in the food chain, posing a serious threat to human health and the ecological environment. Although traditional laboratory testing is accurate, it has problems such as long cycles, high costs, and dependence on professional personnel, which make it difficult to meet the urgent needs of grassroots units for rapid screening and on-site supervision. To solve this difficult problem,Grain heavy metal detectoremerge as the times require.

1、 Product Introduction:

Grain heavy metal detectorAdopting the principle of fluorescence quantitative rapid detection, mainly detecting fungal toxins, heavy metals, pesticide residues, antibiotics, etc. in food; This device is widely used in vegetable wholesale markets, supermarkets, shopping malls, food and drug supervision, local grain depots, grain production enterprises, feed mills, various animal husbandry enterprises, flour mills, food processing plants, third-party testing institutions, and government regulatory departments at all levels;

2、 Instrument features

1. The Android touch system combined with a large-sized high-definition screen has a user-friendly interface, simple and smooth operation, and does not require external devices;

2. 6 channels can simultaneously detect different items, significantly improving detection efficiency and meeting the need for rapid processing of batch samples;

3. Scan and input sample information with QR code to avoid manual errors

4. 8GB of ultra large capacity memory, supports flexible querying, previewing, and deleting results by date, and generates diverse professional reports.

5. Equipped with a built-in thermal printer, standard reports can be printed on-site upon completion of testing, improving work efficiency.

6. Real time self diagnostic function of key components ensures long-term stable operation of the instrument.

7. Build a comprehensive data monitoring platform with high-speed wired/wireless networks and Bluetooth, enabling real-time data uploading, remote querying, statistical analysis, and collaborative supervision.

8. Rich interface design, easy to connect to computers, USB drives, networks, and upper computer systems, supporting USB drive export.

9. The incubation module provides a precise temperature environment for specific test strip reactions.

10. Streamlined structure, compact and lightweight, balancing laboratory durability and testing needs.

11. Card insertion judgment: If the detection card is not inserted into the detection channel, it cannot have built-in quality control function. It can be sent for inspection by the device, self checked by the device, or self checked by the reagent card. Testing methods: incubation testing, real-time testing (re inspection and verification of testing data)

12. Detection curve: It can verify the detection of reagent cards and prevent misjudgment

13. Test results: Report the test items, concentration of the tested substance, testing unit, inspected unit, inspector, testing time, detection limit, and other information that can be displayed on the touch screen and output through the instrument's built-in printer

14. Project management: Support testing project expansion functions

15. Interface settings: The title and footer information can be modified to flexibly display instrument information
