Main parameters:

1. With the continuous improvement of people's living standards, the market has become increasingly strict in controlling tea. In response to the current situation, the commonly used pesticide residue detectors in the market cannot exclude the interference of tea pigments during the detection process, especially for the detection of dry tea. Our company specializes in the research and development of a pesticide residue rapid testing instrument specifically designed for tea; Targeting tea farmers, tea merchants, and tea enterprises for use.

In addition, it can also be used for on-site testing in fruit and vegetable tea production bases and agricultural wholesale sales markets, as well as safety speed testing before fruit and vegetable processing in restaurants, schools, canteens, and households.

2. Detection channels: 12 detection channels, capable of testing multiple samples simultaneously. Each sample is controlled by a program to work independently without interfering with each other.

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

4. Android intelligent operating system, adopting more user-friendly operation, equipped with embedded high-speed thermal printer, can choose manual printing or automatic printing, and print results in three minutes.

5. The light source adopts imported ultra high brightness light-emitting diodes, which have the advantages of low power consumption, strong stability, high sensitivity, high detection accuracy, high repeatability accuracy, controllable light source, and fast response speed.

6. Adopting standard USB interface design, no driver installation, convenient data storage and movement, and can be directly connected to a computer at any time, and the instrument can be controlled by a computer. Implement data query, browsing, analysis, statistics, printing, etc.

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

8. Built in powerful database allows for direct selection of sample names, detection indicators, and inspection units on the instrument, as well as direct editing and input of sample names, detection indicators, inspection units, and other information into the sample database.

9. Wifi networking is supported, data can be uploaded via LAN and Internet, and the test results can be directly transmitted to the food safety supervision platform. Conduct regional food safety supervision and big data analysis processing, detect the long-term and short-term dynamics of regional food safety, and achieve food safety problem estimation and early warning
