Problems solved by technology
[0008] It can be seen from the above-mentioned standardized detection operations that there are major defects in the prior art, such as the inability to guarantee the chemical reaction temperature of the pesticide residue test card, the manual operation of the test greatly reduces the efficiency, and the operators of different levels are not suitable for the test. The results have a certain impact, and testers with different experience often have different results

Description
technical field [0001] The invention relates to the technical field of detection devices, in particular to a portable pesticide residue detection device. Background technique [0002] With the gradual improvement of people's material living standards, the demand for agricultural products is increasing, and the rapid development of agricultural industrialization has made the production of agricultural products more and more dependent on exogenous substances such as pesticides, antibiotics and hormones; China's pesticide homogenization is in the The apportioned amount of agricultural products remains high, and the unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumers' food safety, and in severe cases, causing consumers to become ill, develop abnormally, and even directly lead to poisoning death , is also the culprit for the significant increase in the infertility rate among young people in recent...
