Tea polyphenol detection instrument

Instrument Introduction:

The YT-F12 tea polyphenol detector can quickly and quantitatively detect the content of tea polyphenols in various tea beverages, dairy drinks, fruits and vegetables, grain products, meat products, edible oils, etc. Tea polyphenol detectors can be widely used in product quality supervision and inspection, industrial and commercial management, tea wholesale markets, tea deep processing bases, beverage enterprises, supermarkets, shopping malls, major food safety monitoring systems, and other departments.

Function Introduction:

1. The Android intelligent operating system adopts more efficient and user-friendly operation. The instrument has network cable connection, WiFi networking upload, GPRS wireless remote transmission function, and can quickly upload data.

2. High degree of intelligence, the instrument has self checking function: it has power on self checking and zero setting functions, and has automatic detection of repeatability.

3. Detection channels: ≥ 12 detection channels, capable of testing multiple samples simultaneously. Each sample is controlled by a program and operates independently without mutual interference.

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

5. Equipped with a new generation of embedded thermal printer, you can choose to print manually or automatically. After the detection is completed, you can automatically print the detection report and QR code.

6. The light source adopts imported ultra-high brightness light-emitting diodes, which have high accuracy, strong stability, controllable light source, and can turn off unused light sources, resulting in lower power consumption.

7. Adopting USB2.0 interface design, it is convenient for data storage and movement, and can be directly connected to a computer at any time, and can be used to control instruments by a computer. Implement data query, browsing, analysis, statistics, printing, etc.

8. The instrument has a menu library of multiple types of samples, allowing for flexible selection of testing samples. Different testing channels can simultaneously test different sample items.

9. The 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 type high-precision optical sensor.

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

12. The result judgment line can be modified, the calibration value of the reference value can be saved, and data will not be lost after power outage.

 Main parameters:

1. The main control chip adopts ARM Cortex-A7, RK3288/4 core processor, with a main frequency of 1.88GHz, faster operation speed, and stronger stability.

2. Display method: 7-inch LCD touch screen display, user-friendly Chinese operation interface, intuitive and simple reading.

3. DC 12V power supply, can be equipped with a 6Ah large capacity rechargeable lithium battery.

4. Automatic adjustment and calibration of light source brightness.

5. Intelligent constant current voltage regulation, automatic calibration of light intensity, long-term continuous operation of the light source without temperature drift phenomenon.

6. Sample numbers are automatically accumulated.

7. The detection items can be expanded.

8. The detection results can be printed and uploaded in batches.

9. The test results are in an Excel spreadsheet, which can be copied by connecting to a computer.

10. Supports USB storage, standard USB interface, and driver free installation.

11. Configurable large capacity lithium battery, firmware upgradable
