Pigment detector

Product introduction:

The pigment detector can quickly and quantitatively detect the content of artificial synthetic pigments such as lemon yellow, sunset yellow, carmine, amaranth, allura red and brilliant blue in food.

At present, the synthetic pigments allowed for use in my country are amaranth, carmine, lemon yellow, sunset yellow and indigo. They are used for fruit water, fruit powder, fruit juice, soda, mixed wine, red and green silk, canned food, and pastry surface coloring. These synthetic pigments do make the surface of food look particularly attractive, but they are prohibited from being used in the following foods: meat and its processed products (including processed offal products), fish and its processed products, fruits and their products (including juice, preserved fruit, jam, jelly and brewed fruit wine), condiments, infant food, biscuits, etc.

3. Equipped with a new generation of embedded thermal printer, you can choose manual printing or automatic printing, and the test report and QR code can be automatically printed after the test is completed.

4. The light source adopts imported ultra-bright light-emitting diodes, which are high-precision, stable, controllable, and can turn off unused light sources, with lower power consumption.

5. The USB2.0 interface design is adopted to facilitate the storage and movement of data, and can be directly connected to the computer at any time, and the instrument can be controlled by the computer. Realize data query, browsing, analysis, statistics, printing, etc.

6. The instrument has a supervision platform. Data can be uploaded to the local area network and the Internet, and the test results are directly transmitted to the food safety supervision platform. Carry out regional food safety supervision and big data analysis and processing, detect the long-term and short-term dynamics of regional food safety, and achieve food safety problem estimation and early warning

7. Integrated portable rapid testing equipment to meet the needs of on-site and mobile testing, can realize the detection of all test items under the same software, and can intuitively display the test results through the same window.

8. The instrument has a multi-category and multi-category sample menu library, which can flexibly select test samples, and different test channels can detect different sample items at the same time. You can also directly edit and enter sample names, test indicators, inspection units and other information on the instrument and save them in the sample database.

9. Sample processing is simple and labor-saving, and the overall operation is fast, safe and convenient.

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

11. The instrument has the functions of recalibration, locking, and restoring factory settings.
