1. Product introduction

Testing standard: According to the national standard method (GB/T5009.199-2003) and the requirements of the World Health Organization WHO, the World Food and Agriculture Organization FAO pesticide residue testing standards, and the World Environmental Protection Agency EPA reference intake, etc. The enzyme inhibition rate colorimetry is used to quickly and accurately detect the content of organophosphorus and carbamate pesticides in fruits, vegetables and other agricultural and forestry products.
is widely used for the rapid detection of organophosphorus and carbamate pesticide residues in vegetables, fruits, tea leaves, grains, agricultural and sideline products and other foods; in addition, it can also be used for on-site testing of fruit and vegetable tea production bases and farmers' wholesale sales markets, and safe and quick testing before processing in restaurants, schools, canteens, and families.
Second, performance description
1, acetylcholinesterase and butyrylcholinesterase reagents can be used, in line with national standards and standards of the Ministry of Agriculture.
2, automatically determine whether the sample is qualified, the test results are more intuitive.
3, the instrument has more than 100 kinds of vegetable name menu library, classification management, and can add or delete vegetable names on demand, edit vegetable names, can directly print out vegetable names.
4, detection channels: 24 detection channels, can test multiple samples at the same time, cycle detection, that is, release and check, each sample is controlled by the program to work independently, will not interfere with each other.
5, Android intelligent operating system, using more user-friendly operation, the main control chip uses ARM Cortex-A7, RK3288/4 core processor, the main frequency is 1.88Ghz, the operation speed is faster and the stability is stronger.

6, display mode: 7-inch high-sensitivity true-color touch screen display, humanized Chinese operation interface, the reading is intuitive and simple.
7, the printer adopts serial port 5v printing, you can choose manual printing or automatic printing, three minutes out of the print result, the print format is the name of the detector, the difference in absorbance, the detection time, the detection mechanism, the name of the sample and the result judgment, the QR code can be printed, and the detailed print content can be displayed by scanning the code on the mobile phone.
8, the light source adopts imported ultra-bright Light Emitting Diode, which has the advantages of low power consumption, high precision, strong stability, controllable light source can turn off the unused light source, and fast response speed.
9, Intelligent constant current voltage regulation, automatic calibration of light intensity, long-term continuous working light source without temperature drift phenomenon.
10, the instrument has GPRS remote transmission function, can be inserted into the mobile phone card to realize the data remote transmission platform, wifi networking function, can quickly upload the data to the computer for data management and statistics.
11, USB2.0 interface design is adopted, which is convenient for data storage and movement, and can be directly connected to the computer at any time, and can be controlled by the computer. Realize data query, browsing, analysis, statistics, printing, etc.
12, high degree of intelligence, the instrument has self-test function: with boot self-test and zero function, with automatic detection of repetitive function
13, the instrument has its own protection function, can set user name and password to prevent non-staff operation, etc.

14, channel 1 to channel 6, each channel error is 0, the repeatability of each channel is 0 to 0.2, the photoelectric drift stability between each channel 0-0.1 (with the authoritative report issued by the National Institute of Metrology).
15, using DC12v DC power supply, higher safety system, and optional built-in large-capacity 6A lithium battery power supply.
16, the instrument has the function of recalibration, locking, and restoring factory settings.

17, the instrument has the copyright of food safety software.

18, the instrument has a measurement report issued by the National Institute of Metrology.

19, the manufacturer has independent trademark intellectual property rights.
