The grain freshness detector is a special instrument to detect the freshness of rice. It is mainly used to evaluate the freshness of rice in grain depots, seed depots, rice processing enterprises, grain quality inspection centers, colleges and research institutions, etc. It is applicable to japonica and indica rice.
1. The dual wavelength test is more accurate: the grain freshness detector adopts a dual-wavelength contrast test, and the monitoring results are accurate and objective, and its accuracy reaches the 1% standard of the same level in Europe, America, and Japan.
2. High stability of light source: the instrument is equipped with a corresponding imported power supply to ensure its stability.
3. Large LCD touch screen: 7-inch LCD touch screen, with a clear interface and fast operation.
4. Automatic data calculation: the system automatically calculates the results, which are visible.
5. Built-in thermal printer: sample test results can be printed at any time.
6. Supporting self-made reagents, safe and reliable: save configuration time, and the dosage can detect no less than 100 samples.
7. Large capacity data storage: no less than 100000 pieces of data can be stored, which can be stored, viewed, and deleted locally through the instrument.
