A ﹑ machine Name: fruit and vegetable pesticide residues detector II Model: CSY-N8 three, fruit and vegetable pesticide residue testing instruments Introduction: CSY-N8 pesticide residues detector according to standard methods based on agriculture (NY / T 448-2001) and national standards (GB / T5009.199-2003) of enzyme inhibition rate method, strictly abide by the "vegetable organophosphorus and carbamate pesticide residues rapid test standard" the requirements for pesticide residues in vegetables organophosphate and carbamate Rapid Determination. Is the first generation of pesticide residues detector upgrade products, can accurately and quickly detect the rapid detection of vegetables, fruits, grains, tea and soil organic phosphorus and carbamate pesticide residues in lipids. Fruit and vegetable pesticide residues detector can be widely used in all levels of government testing center vegetables, farmers markets, supermarkets, environmental agencies, vegetable planting base, hotel, car and food safety testing laboratories and other units of measurement and monitoring sites for pesticide residues in fruits and vegetables . Fourth, the fruit and vegetable pesticide residues detector principle: pesticide residue detector enzymatic reaction kinetics based on the principle of the test sample as containing phosphorus or carbamate pesticides, will inhibit cholinesterase activity, affecting the color system The reaction rate by measuring the absorbance of the color system to measure the time rate of change of the sample of pesticide residues (inhibition). _ Organophosphate and carbamate pesticides on the normal function of cholinesterase inhibition, inhibition rate and pesticide concentrations showed a positive correlation. Under normal circumstances, the enzymatic neurotransmitter metabolites (acetylcholine) hydrolyzing reagent reaction hydrolyzate thereof, to give a yellow substance, measuring the absorbance change value with time pesticide residue testing instrument to calculate the inhibition ratio by the inhibition rate based on whether the sample contains the presence of organophosphate or carbamate pesticides. Five, fruit and vegetable pesticide residues Detector Specifications: ☆ accuracy error: ± 3% ☆ Linearity error: ± 5 ‰ ☆ Stability: ± 0.001A / hr ☆ Wavelength Accuracy: <2.0nm ☆ absorbance range: 0.000 ~ 4.000ABS ☆ Wavelength range: 410nm ± 2nm ☆ Transmittance Repeatability: ± 1% ☆ ☆ sample data storage 80,00 stripe detection time: ≤3 minutes ☆ cuvette: 10 × 10mm standard cuvette ☆ Dimensions: 350X290X130 (mm) ★ fruit and vegetable pesticide residue detector using the new instrument design, small size, easy to carry. No mechanical moving parts, jamming, anti-vibration, ★ 8-channel design, and start and single were started two measurement modes. When multiple sample measurements, customers can operate proficiency, self-select the measurement mode, the maximum coefficient of variation between channels eliminate caused by measurement error. ★ high accuracy: imported special LED light source, with good wavelength accuracy and repeatability, and comprehensively improve the accuracy of test results. ★ fruit and vegetable pesticide residues detector high degree of automation: the instrument automatically diagnose system faults, Wavelength Calibration: automatic calibration instrument ★ Long life: LED light source, automatic switch energy saving design, the non-continuous mode. ★ life of up to 10 years more than 8000 instrument automatically stores the measurement data. Built-in mini thermal printer, lifelong need to replace the ribbon, you can print the test results in real-time test report can be printed vegetable names, inhibition rate, eligibility, testing dates, testing units. Test results better reflect the authority and pesticide residues in fruits and vegetables in favor of publicity ★ detector equipped with RS-232 interface and a USB port for data processing by computer, statistical analysis, and upload the results. The company as matching food safety monitoring network software, you can set up networks at various levels according to user requirements provinces, municipalities, the county and the like. http://www.csy17.com
