Testing standards: designed according to the national standard method (GB/T5009.199-2003) and the World Health Organization WHO, the FAO FAO residual pesticide testing standards, the World Environmental Prowtection Agency EPA reference intake and other requirements.
The enzyme inhibition rate colorimetric method was used to quickly and accurately detect the content of organophosphorus and carbamate pesticides in agricultural and forestry products such as fruits and vegetables.
Widely used in the rapid detection of organophosphorus and carbamate pesticide residues in foods such as vegetables, fruits, tea, food, agricultural and sideline products;
In addition, it can also be used for on-site inspection of fruit and vegetable tea production bases and farmer wholesale sales markets, safe and rapid detection before restaurants, schools, canteens, family fruits and vegetables. 

2. Performance description: 

1.Acetylcholinesterase and butyrylcholinesterase reagents can be used, in line with national standards and the requirements of the Ministry of Agriculture standards. 

2.Automatically judge whether the sample is qualified or not, and the test result is more intuitive. 

3.The instrument has more than 100 kinds of vegetable name menu library, classification management, and can add or delete vegetable names as needed, edit the vegetable name, you can directly print out the vegetable name. 

4.Detection channel: 6/8/10/12/16/20/24 detection channels, can test multiple samples at the same time, cycle detection, that is, release inspection, each sample is independently controlled by program control, and will not interfere with each other. 

5.Intelligent operating system, using more humanized operation, the main control uses a multi-core processor, the main frequency of 1.88Ghz, faster operation, more stable. 

6.Display mode: 7-inch high-sensitivity true color touch screen display,readings are intuitive and simple. 

7.The printer adopts serial port 5v printing. It can choose manual printing or automatic printing. The printing result is output in three minutes. The printing format is the name of the inspector, the difference in absorbance, the detection time, the detection mechanism, the sample name and the result judgment. 

8.The light source adopts imported super bright LED, which has the advantages of low power consumption, high precision, strong stability, controllable light source, can turn off the unused light source, and has fast response speed. 

9.Intelligent constant current regulator, light intensity automatic calibration, long-term continuous working light source without temperature drift phenomenon. 

10.Using USB2.0 interface design, convenient for data storage and movement. Realize data query, browsing, analysis, statistics, printing, etc. 

11.High degree of intelligence, the instrument has a self-test function: with power-on self-test and zero adjustment function, with automatic detection of repeatability 

12.The instrument has its own protection function, which can set the user name and password to prevent non-workers from operating. 

13.using DC12V DC power supply, higher security system, and equipped with 6A lithium battery charger. 

14.The instrument has the functions of recalibration, locking, and factory reset.
