Multi-parameter food safety detector

Product application

This multi-functional food safety detector is an integrated rapid detection and analysis device for food safety, widely used by units such as the Food and Drug Administration, health departments, higher education institutions, research institutes, agricultural departments, farms, slaughterhouses, deep processing enterprises of food and meat products, and inspection and quarantine departments.

Testing items

It can quickly detect the content of formaldehyde, sodium dithionite, sulfur dioxide, nitrite, hydrogen peroxide, borax, pesticide residues in various foods, protein, nitrate and heavy metal lead in milk and dairy products. The instrument reserves detection programs and ports for other items, and it is convenient to add detection items independently according to future needs.

4. Display mode: ≥ 8-inch LCD touch screen display, with a user-friendly Chinese operation interface, making readings intuitive and simple.

5. Equipped with a new generation of embedded thermal printer, it can be selected for manual or automatic printing. After the test is completed, the test report and QR code can be automatically printed.

6. The light source adopts imported ultra-bright light-emitting diodes, featuring high precision, strong stability, controllable light source, and the ability to turn off unused light sources, resulting in lower power consumption.

7. It adopts a USB2.0 interface design, which is convenient for data storage and movement. It can be directly connected to a computer at any time and the instrument can be controlled by a computer. Realize data query, browsing, analysis, statistics, printing, etc.

8. The instrument is equipped with a supervision platform. The data can be uploaded via local area network and the Internet, and the test results are directly transmitted to the food safety supervision platform. Conduct regional food safety supervision and big data analysis and processing, monitor the long-term and short-term dynamics of regional food safety, and achieve the prediction and early warning of food safety issues

9. The integrated portable rapid testing device meets the on-site and mobile testing requirements. It can perform all testing items under the same software and display the testing results intuitively through the same window.

10. The instrument features a multi-category and multi-type sample menu library, allowing for flexible selection of samples to be tested. Different detection channels can simultaneously test different sample items. The sample name, detection indicators, submitting unit and other information can also be directly edited and entered on the instrument and saved into the sample database.

11. Sample processing is simple and effortless, and the overall operation is fast, safe and convenient.

12. The instrument has self-protection functions. Users can set usernames and passwords to prevent non-staff from operating it, etc.

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

14. The instrument is equipped with the functions of re-calibration, locking and restoring factory Settings.

15. Supports USB flash drive storage. The result determination line can be modified, the reference value calibration value can be saved, and the data will not be lost in case of power failure.

Main parameters
