Pesticide Residue Tester

Product Details

Name: Pesticide Residue Tester

Model:NY-8DA

1. Principle of Instrument

Pesticide Residue Meter 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
