Handheld Pesticide Residue Tester

Principle of Instrument
This  Handheld Pesticide Residue Rapid Tester is based on cholinesterase hydrolyzing acetylcholine. Its hydrolysate impacts DTMB, forming the yellow coupling things. Organophosphate pesticide can control enzyme. The changes of absorption value can show the degree of controlled enzyme and then reflect the pesticide residue in samples.
Area of Application
Inspected products: Agricultural and sideline products, daily food, seafood and its products and so on.
Inspected object: Rapid quantitative testing of organophosphate and carbamate pesticide residues.
Applicable units: Departments of industry and commerce, hygiene, quality supervision, agriculture, trade and so on; Trade markets, supermarkets, wholesale markets for agricultural products, hotels, large dining rooms, bases for agricultural production and so on.
