characteristic:

★ Microcomputer control, programmed design, 5.1-inch large screen with Chinese characters backlit display, AC/DC dual-use, built-in lithium battery, capable of field flow testing.

★ No need for blank and standard calibration, one click operation, direct data reading, complete set of accessories and finished drugs.

★ High brightness LED light source is used to ensure stable wavelength of the light source. Silicon semiconductor is used as the signal receiving system, with a lifespan of up to 100000 hours. The light source is stable, with good reproducibility and high accuracy.

The colorimetric groove adopts a dual channel four light path design, with no mechanical displacement or wear. The light path testing is well positioned to ensure the accuracy of the measurement results.

★ Built in crop expert fertilization system, directly derive scientific fertilization formula based on test results. Based on the fertilizer requirements of crops themselves and the soil's fertilizer supply capacity, as well as fertilization theory and the latest guidance from the Ministry of Agriculture's soil testing and formula fertilization expert group, a corresponding fertilization plan is recommended based on soil testing data. Compared with existing expert systems, it is more flexible and scientifically rational.

★ Touch sensitive buttons, built-in thermal printer, can print test results and fertilization suggestions, with historical query function.
