Tea polyphenols testing instrument

Instrument introduction:

HM-F12 tea polyphenols testing instrument can quickly and quantitatively detect the content of tea polyphenols in various tea beverages, milk drinks, fruits and vegetables, grain products, meat products, edible oils and fats. Tea polyphenols detector can be widely used in product quality supervision and inspection, industrial and commercial management, tea wholesale market, tea 0. Deep processing base, beverage enterprises, supermarkets, shopping malls, major food safety monitoring systems and other departments.

Function introduction:

1. Android smart operating system, using more efficient and humanized operation, the instrument has network cable connection, wifi network upload, GPRS wireless remote transmission function, fast data upload.

2. High degree of intelligence, the instrument has self-test function: it has power-on self-test and zero adjustment function, and has automatic detection repeatability function.

3. Detection channel: ≥12 detection channels, multiple samples can be tested at the same time, each sample is controlled by the program to work independently and will not interfere with each other.

4. Display mode: ≥7-inch LCD touch screen display, humanized Chinese operation interface, intuitive and simple reading.

5. 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.

6. 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.

7. 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.

8. The instrument has a variety of sample menu libraries, which can flexibly select test samples, and different test channels can detect different sample items at the same time.

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.

12. The result judgment line can be modified, the control value calibration value can be saved, and the data will not be lost when the power is off.
