Wat Sc03 Handheld Resticide Residue Tester - China

The pesticide residue rapid tester is specially designed according to the technical requirements of enzyme inhibition rate (spectrophotometry) in the national standard GB/T 5009.199-2003, the content of organophosphorus and carbamate pesticides in fruits and vegetables can be detected quickly and accurately.

The instrument can be widely used in vegetable inspection centers, farmers markets, supermarkets, environmental protection, vegetable cultivation bases, hotels and other units to determine pesticide residues in fruits and vegetables.

Under certain conditions, Organophosphorus and carbamate pesticides inhibit the normal function of cholinesterase, the inhibition rate was positively correlated with the concentration of pesticides.

Under normal circumstances, enzyme catalyzed neurotransmitter medium hydrolyze, the hydrolysate reacts with the chromogenic agent, produce yellow substance, Determination with pesticide residue fast tester the absorbance changes with time value (A) to calculate the inhibition rate (I), through the inhibition rate can judge is there a high dose of organophosphorus or carbamate pesticides present in the sample.

;

I——Inhibition rate of enzyme;

△A0——Contrast the change of absorbance of solution with time;

△Aτ——Value of absorbance of sample solution change with time;

The instrument consists of a LED light source, a colorimetric cell, a photoelectric sensor, a microprocessor and a micro printer, can be displayed directly on the LCD screen the inhibitory rate of the tested sample to the enzyme and print the results.

2 - Characterisitics

1)The instrument is controlled by single chip microcomputer, with measurement, settings, automatic storage, inquiries and other functions;

2)The light source adopts led, has the advantages of energy saving, environmental protection, long service life, fast response, etc.

;

3)Interface humanization, visual reading;

4)Reagent kit color, sample and reagent dosage is little, prevent the twice pollution;

5)Built in battery powered, body design is compact and light, portable and convenient;

6)Easy to operate and quick to detect, non professionals are also quick to master tests；

7)Provide a complete portfolio of components and durable tool kit, Convenient for field scene and laboratory quantitative tests.
