Portable pesticide residue detector analyzes pesticide residues in fruits and vegetables

With people's increasing concern about food safety, the problem of pesticide residues in fruits and vegetables has become a social focus. Portable pesticide residue detectors provide reliable technical support for the safety monitoring of fruit and vegetable products from the field to the table with their fast, accurate and convenient characteristics.

The portable pesticide residue detector adopts the principle of enzyme inhibition rate colorimetry and is designed according to national standards (GB/T5009.199-2003) and international standards such as WHO and FAO. It can quickly detect organophosphorus and carbamate pesticide residues. The instrument supports the dual reagent system of acetylcholinesterase and butyrylcholinesterase to ensure that the test results meet the national and Ministry of Agriculture standards. Its industrial-grade ABS engineering plastic box design not only ensures the stability and durability of the equipment, but also is easy to carry, which is very suitable for on-site mobile testing.

In fruit and vegetable production bases, portable pesticide residue detectors play an important role. The instrument is equipped with a menu library of more than 100 vegetable and fruit names, which can intelligently adjust parameters according to different test objects to ensure detection accuracy. The design of 6 independent detection channels supports simultaneous detection of multiple samples, greatly improving work efficiency. The Android smart operating system and 7-inch touch screen make the operation easier and more intuitive, and even non-professionals can quickly master it. The test results can be automatically determined and printed within 3 minutes, including key information such as sample name, test time and result determination, providing timely drug use guidance for agricultural producers.

Farmers' markets and supermarkets are another important application scenario for portable pesticide residue detectors. The built-in WiFi and 4G networking functions of the instrument can upload the test data to the supervision platform in real time, realizing remote monitoring and big data analysis of the test results. The imported high-brightness LED light source and intelligent optical calibration system ensure the accuracy and stability of the test and effectively avoid misjudgment. The multi-core processor (1.88GHz main frequency) ensures smooth operation of the equipment and meets the fast-paced testing needs of the market.

It is particularly worth mentioning that the application of this instrument in collective canteens and catering units has achieved remarkable results. By using portable pesticide residue detectors in schools, restaurants and other places, rapid screening can be carried out before food processing to effectively prevent food safety accidents. Intelligent constant current voltage stabilization technology enables the instrument to work stably for a long time to meet the needs of large-scale testing. The light source temperature drift control technology ensures the consistency of the test results and avoids detection deviations caused by environmental changes.

The emergence of portable pesticide residue detectors has enabled pesticide residue detection to move from laboratories to fields and markets, greatly improving the timeliness and coverage of food safety supervision. Its fast and accurate detection capabilities provide strong support for building a full-chain food safety assurance system from production to consumption.
