1、 Product Introduction:

Testing standards: Designed based on national standard methods (GB/T5009.199-2003) and requirements such as the World Health Organization (WHO), the Food and Agriculture Organization of the United Nations (FAO) residue pesticide testing standards, and the World Environmental Protection Agency (EPA) reference intake. The enzyme inhibition rate colorimetric method is used to quickly and accurately detect the content of organic phosphorus and carbamate pesticides in agricultural and forestry products such as fruits and vegetables.

Widely used for rapid detection of organophosphate and carbamate pesticide residues in foods such as vegetables, fruits, tea, grains, and agricultural products; 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、 Performance Description:

1. Acetylcholinesterase and butyrylcholinesterase reagents can both be used, meeting the requirements of national standards and the standards of the Ministry of Agriculture.

2. The Android intelligent operating system adopts more user-friendly operation, and the main control adopts a multi-core processor with a clock speed of 1.88GHz, which runs faster and has stronger stability.

3. The instrument has 4G wireless remote transmission, WiFi network upload, and Ethernet cable connection functions, which can quickly upload data for data management and statistics.

4. Automatically determine whether the sample is qualified, making the test results more intuitive.

5. The instrument has a menu library of over 100 vegetable names, classified management, and can add or delete vegetable names as needed, edit vegetable names, and directly print out vegetable names.

6. Detection channels: 8 detection channels, capable of testing multiple samples simultaneously, with cyclic detection, i.e. immediate testing. Each sample is controlled by a program to work independently without interfering with each other.

7. Display mode: 7-inch high-sensitivity true color touch screen display, user-friendly Chinese operation interface, intuitive and simple reading.

8. The new generation high-speed printer can simultaneously print QR codes in the format of the name of the tester, absorbance difference, testing time, testing institution, sample name, and result judgment.

9. The light source adopts imported ultra high brightness light-emitting diodes, which have the advantages of low power consumption, high precision, strong stability, controllable light source that can turn off unused light sources, and fast response speed.

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

11. Designed with USB 2.0 interface, it is convenient for data storage and movement, and can be directly connected to a computer at any time. The instrument can also be controlled by a computer. Implement data query, browsing, analysis, statistics, printing, etc.

12. 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

13. The instrument has its own protection function, which can set a username and password to prevent non staff operations.

14. Adopting DC12V DC power supply, the safety system is higher and equipped with a 6A lithium battery charger.

15. The instrument has the functions of recalibration, locking, and factory reset.
