Rapid pesticide residue analyzer

Product Introduction:

Testing standards: Designed based on national standard methods (GB/T5009.199-2003), as well as the World Health Organization (WHO), Food and Agriculture Organization (FAO) residue pesticide testing standards, and the World Environmental Protection Agency (EPA) reference intake requirements. 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. Acetylcholinesterase and butyrylcholinesterase reagents can be used, meeting the requirements of national standards and the standards of the Ministry of Agriculture.

Widely used for rapid detection of organic phosphorus and carbamate pesticide residues in foods such as vegetables, fruits, tea, grains, and agricultural by-products; In addition, it can also be used for on-site testing in fruit and vegetable tea production bases and agricultural wholesale and sales markets, as well as safety rapid testing before processing fruits and vegetables in restaurants, schools, canteens, and households.

Performance description:

1. The chassis is made of industrial grade ABS engineering plastic box, which is easy to carry, stable and durable, and convenient for flow testing.

2. The Android operating system adopts a more user-friendly operation, with a multi-core processor and a main frequency of 1.88GHz for faster operation speed and stronger stability.

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

4. The instrument has a menu library of over 100 vegetable names, which is classified and managed. It can also add or delete vegetable names as needed, edit vegetable names, and directly print vegetable names.

5. Detection channels: 6 detection channels, which can test multiple samples simultaneously and perform cyclic testing, that is, release and check. Each sample is controlled by the program to work independently without interfering with each other.

6. The instrument has WiFi networking function, which can quickly upload data to the computer for data management and statistics. It also has 4G signal GPRS remote transmission function and can be plugged into a mobile phone card to achieve data remote transmission platform,.

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

8. The printer adopts a 5V serial port for printing, and can choose to print manually or automatically. The printing result is generated in three minutes, with the printing format including 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, and can turn off unused light sources with fast response speed.

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

11. Adopting USB2.0 interface design, it facilitates data storage and movement, and can be directly connected to a computer at any time, and can be used to control instruments. Implement data queries, browsing, analysis, statistics, printing, and more.

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

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

14. Using DC12v DC power supply, the safety system is higher and can be equipped with a 6A lithium battery charger.

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