School is about to start, and the safety inspection of the school canteen must be strictly conducted. In addition to ensuring the freshness of food, it is also necessary to ensure that the pesticide residue content of the purchased vegetables is up to the standard. Nowadays, in the production or storage of agricultural products, problems with the use of highly toxic pesticides or the use of banned pesticides have been discovered. The safety of the cafeteria has gradually become an important part of maintaining campus safety. If food poisoning or poor hygiene quality often occur in college canteens, it will not only directly affect the reputation and status of the school, but also seriously endanger the physical and mental health of students. Therefore, school canteens must also be equipped with a special pesticide residue detector for vegetable pesticide residue detection.
It is understood that the pesticide residue detector mainly uses the enzyme inhibition rate colorimetric method to quickly and accurately detect the content of organophosphorus and carbamate pesticides in fruits, vegetables and other agricultural products. The instrument has a built-in thermal high-speed printer (without changing the ribbon) that can print bar codes, and the host screen displays: vegetable name, inhibition rate, pesticide content (quantitative), qualification, test date, test unit (can be modified on the host), latitude and longitude, temperature Humidity, radiation and other parameters. It can be widely used in school canteen vegetable inspection, product quality supervision and inspection, hygiene and epidemic prevention, environmental protection, business management, vegetable wholesale market, etc. 
Pesticide residue detectors "escort" the safety of catering in school cafeterias
Pesticide residue has always been a topic that people are more concerned about, because it is related to diet safety. In the process of planting fruits and vegetables, many growers often use pesticides to kill pests in order to prevent and control pests and to ensure yield. As a result, the problem of pesticide residues also arises. Fortunately, in recent years, the rapid testing technology of pesticide residues has become more and more mature, and the pesticide residue content on the surface of fruits and vegetables can be determined by a special pesticide residue detector .
