Multi-channel pesticide residue rapid detector

Product Introduction:

Testing Standard: Designed according to the national standard method (GB/T5009.199-2003) and the World Health Organization WHO, the World Food and Agriculture Organization FAO pesticide residue detection standards, the World Environmental Protection Agency EPA reference intake requirements. The enzyme inhibition rate colorimetry method is used to quickly and accurately detect the content of organophosphorus and carbamate pesticides in agricultural and forestry products such as fruits and vegetables. Both acetylcholinesterase and butyrylcholinesterase reagents can be used, which meets the requirements of national standards and Ministry of Agriculture standards.

Widely used for rapid detection of organophosphorus and carbamate pesticide residues in foods such as vegetables, fruits, tea, grain, and agricultural and sideline products; in addition, it can also be used for on-site detection of fruit and vegetable tea production bases and agricultural trade wholesale sales markets, restaurants, schools, canteens, and family fruit and vegetable processing safety rapid testing.

Performance Description:

1. The chassis adopts industrial-grade ABS engineering plastic box, which is easy to carry, stable and durable, and convenient for mobile testing.

2. Android operating system, more user-friendly operation, the main control adopts multi-core processor, main frequency 1.88Ghz, faster operation speed and stronger stability.

3. Automatically judge whether the sample is qualified, and the test results are more intuitive.

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

5. Detection channel: 18 detection channels, can test multiple samples at the same time, cycle detection, release and test, each sample is controlled by the program to work independently, and will not interfere with each other.

6. The instrument has wifi networking function, which can quickly upload data to the computer for data management and statistics, 4G signal GPRS remote transmission function, and can insert mobile phone cards to realize data remote transmission platform.

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

8. The printer uses serial port 5v printing, and can choose manual printing or automatic printing. The printing result is available in three minutes. The printing format is the name of the tester, absorbance difference, test time, test organization, sample name and result judgment.

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

10. Intelligent constant current voltage regulation, automatic calibration of light intensity, and no temperature drift of the light source for long-term continuous work.

11. 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.

12. The degree of intelligence is high, and the instrument has self-test function: it has power-on self-test and zero adjustment functions, and has automatic detection repeatability function

13. The instrument has its own protection function, and the user name and password can be set to prevent non-staff operations.

14. It adopts DC12v direct current power supply, with a higher safety system and can be equipped with a 6A lithium battery charger.

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