Name: Pesticide Residue Tester

1. Principle of Instrument
Pesticide Residue Tester is based on cholinesterase catalyzing acetylcholine, its hydrolysate impacts DTNB to form yellow AZO. Organophosphate pesticides has effect on enzyme. Through changes of absorption value show the degree of inhibition and further reflect the pesticide residue in samples. The instrument consist of LED, thermostatic color pool, integrated photoelectric sensors, ARM9 microprocessor and miniature printer and can print directly and transit result of testing.

2. Characteristics
Testing pesticide residue in onion, garlic, ginger, fragrant-flowered garlic, carrot tomato, vegetables 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
