1、 Product Introduction:

The pesticide residue detector produced by Shandong Yuntang Intelligent Technology Co., Ltd. is widely used for rapid detection of pesticide residues in food such as vegetables, fruits, tea, grains, and agricultural and sideline products. It is tested according to the national standard GB/T5009.199-2003 and is suitable for on-site detection in fruit, vegetable, and tea production bases as well as agricultural wholesale and sales markets. It is also used for safety testing in restaurants, schools, canteens, and households before fruit and vegetable processing.

2、 Main technical parameters:

1. The machine adopts a brand new Android intelligent system, and the main control chip adopts ARM Cortex-A7, RK3288/4-core processor, with a main frequency of 1.88GHz, faster operation speed, and stronger stability.

2. Innovative detection mode:

*The instrument adopts a precision rotating colorimetric cell design and uses consistent light sources to solve the problem of detection result errors caused by light source errors between channels, resulting in more accurate detection results.

*The instrument has an automatic recognition colorimetric dish detection function, which means that after placing the sample colorimetric dish into the instrument and clicking on the sample detection button, the instrument automatically recognizes the colorimetric dish for channel detection.

3. Power supply mode: dual-purpose AC/DC, 12V DC power supply, can be connected to car power supply, can be equipped with 6ah large capacity rechargeable lithium battery, convenient for outdoor mobile testing.

4. Display mode: 7-inch LCD touch screen display, user-friendly Chinese operation interface, intuitive and simple reading.

5. Detection channels: 12 detection channels, capable of testing multiple samples simultaneously, with cyclic detection, i.e. immediate release and detection. Each sample is controlled by a program to work independently without interfering with each other.

6. High precision light source system:

① The instrument light source adopts imported ultra high brightness light-emitting diodes, and the brightness of the light source can be automatically adjusted and calibrated

② Intelligent constant current and voltage regulation, automatic calibration of light intensity, and long-term continuous operation of the light source without temperature drift phenomenon.

7. Intelligent operation analysis system:

① The instrument has a menu library of over 100 vegetable names, which can be classified and managed, and vegetable names can be added, deleted, or edited as needed; It is possible to automatically select 1-24 sample names for the corresponding detection channels on the same detection interface without exiting the interface, saving operation time.

② Built in new national limited edition standards, on-site comparison with measured results, and continuous updating of standards.

8. Complete supporting hardware:

① Using a serial port 5V printer, manual printing or automatic printing can be selected, and the printing result will be output in three minutes. The printing format includes the name of the tester, absorbance difference, testing time, testing institution, sample name, and result judgment.

② The instrument has a wireless upload module, and the test results can be printed and uploaded in batches.

9. Data call:

① The instrument can store 200000 test results,

② The test results are presented in an Excel spreadsheet, which facilitates data analysis and summary reporting in the future

③ The instrument adopts a USB2.0 interface design, supports USB storage, facilitates data storage and movement, and can be directly connected to a computer at any time to achieve data query, browsing, analysis, statistics, printing, etc.

10. The firmware of the later product can be upgraded.

11. Safety certificate, reassuring guarantee: The instrument has a calibration certificate from the China Institute of Metrology, ensuring safe use.

12. The chassis is made of industrial grade ABS engineering plastic box, which is easy to carry, stable and durable, and convenient for flow testing.

3、 Performance and features:

1. The Android intelligent operating system adopts more efficient and user-friendly operation, and the instrument has wireless networking upload function, which can quickly upload data for data statistics and analysis.

2. High degree of intelligence, the instrument has self checking function: it has power on self checking and zero adjustment functions, and automatic detection of repeatability function; Meanwhile, upon completion of the inspection, the inspection report and QR code can be automatically printed. Scanning the code with a mobile phone can display detailed detection information.

3. The instrument is equipped with a supervision platform, and the data can be uploaded on the LAN and Internet, and the test results can be directly transmitted to the food safety supervision platform. Conduct regional food safety supervision, big data analysis and processing, and data statistics, detect the long-term and short-term dynamics of regional food safety, and achieve food safety problem estimation and early warning.

4. Sample processing is simple and labor-saving, and the overall operation is fast, safe, and convenient.

5. The instrument has its own protection function, which can set a username and password to prevent non staff operations.

6. Built in powerful database allows for direct selection of sample names, detection indicators, and inspection units on the instrument, as well as direct editing and input of sample names, detection indicators, inspection units, and other information into the sample database for easy retrieval and use in later operations.

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