About Products

Instrument Theory

Pesticide Residue Meter is based on cholinesterase catalyzing acetylcholine, its hydrolysate and DTNB form yellow AZO. Organophosphate pesticides have effect on enzyme. Through changes of absorption value show the degree of inhibition and further reflect the pesticide residue in samples. It consists of LED, thermostatic color pool, integrated photoelectric sensors, ARM9 microprocessor and miniature printer. It is able to print directly and upload testing results.


Testing pesticide residue in onion, garlic, ginger, fragrant-flowered garlic, carrot tomato, etc.
Color reaction under room temperature condition, fast testing speed
Plastic shell, streamline appearance, 6 inch color LCD displayer, easy to operate
High sensitivity to methamidophos, dichlorvos and so on
Adopt ARM9 inserting controlling system, with the function of saving, collecting, processing, analyzing
