Functional indicators: 1. Efficient and fast: It only takes 1-3 minutes to determine various indexes of samples at the same time, which greatly shortens the detection period 2. Scientific precision: The instrument adopts patented sampling technology, automatically collects 5-25 (adjustable) sub-samples for analysis, and combines advanced excellent algorithms to improve the accuracy and stability of the instrument detection results 3. Flexible and diverse: According to the particle size of the sample, the appropriate optical path module of the sample cell can be selected to realize the detection of different samples 4. Non-destructive: Samples can be injected in whole grains without grinding 5. Intelligent analysis: Equipped with special analysis software, with self-checking, model correction, wavelength correction, test, automatic report generation and other functions 6. Intelligent monitoring: Equipped with intelligent monitoring software, with power prompt, temperature and humidity monitoring, automatic calibration of sample temperature and adaptive spectrum balance 7. Easy to operate: Adopt 12-inch capacitive touch screen and windows7 operating system, which can be mastered after simple training 8. Compatible power supply design: meet the application requirements of different occasions and can work outdoors around the clock 9. Support Internet application: USB typeA, USB typeB and RJ45 network interfaces can be provided to access the Internet, which is convenient for daily maintenance of instruments, model upgrade and database update
