Product introduction:
1. Used for the detection of organophosphorus and carbamate pesticide residues in fruits, vegetables and other agricultural products.
The enzyme inhibition rate method in national standards is a sensitive, efficient and accurate method for the rapid detection of pesticide residues in China.
2. Automatic pesticide residue detector can realize the full automation of rapid detection of pesticide residue, with built-in detection reagent such as enzyme, substrate and color reagent, etc. During detection, only samples to be tested need to be put in, and reagent addition, mixing and temperature bath can be completed automatically, which can realize accurate and rapid detection of pesticide residue.
In the detection process, the temperature is constant, the reagent is quantitative, and the automatic cleaning can be realized after the detection process and use, which is simple, fast, stable and reliable, eliminating the error introduced by human factors in the traditional detection.
Ii. Summary of advantages
1. Convenient operation: integrated design of the whole machine, integrated main control system, human-computer interaction system, micro thermal printer, single fully functional independent operation, no need for other peripherals.
2. Technical advantages: the unique patented sample adding and mixing technology is adopted to add samples independently with various reagents.
