2. Adopting a 5.0-inch large screen LCD Chinese display, Chinese guided operation, and built-in expert fertilization software. Recommended fertilizer application rates can be calculated for the target yields of 73 national agricultural, fruit tree, and economic crops.

3. Equipped with a large capacity rechargeable battery, it can work continuously for 4 hours without an external power source.

4. Adopting a USB interface design, it facilitates data storage and movement, and can be directly connected to a computer at any time to achieve data query, browsing, analysis, statistics, printing, and information publishing.

5. Instrument automatic diagnosis system malfunction.

6. Built in micro thermal printer, automatically saves test results, and can print test results in real time.

7. Expert Fertilization System Software

A、 Multiple crop expert fertilization suggestions are stored in memory, which can automatically recommend fertilization plans based on crop varieties, soil content, fertilizer content, and fertilizer prices. It can save more than 1000 items and can also save and print fertilization suggestion forms without restrictions.

B、 It can print out relevant information such as testing date, testing time, customer name, soil number, soil type, crop variety, soil content, fertilizer variety, fertilizer price, fertilizer quantity, etc., with detailed and rich content.

2、 Test project:

It can quickly and quantitatively detect soil, plants, chemical fertilizers, biological fertilizers, available nitrogen, available phosphorus, available potassium, organic matter and other items in water. The salinity, acidity, and moisture content of the soil, as well as the temperature in the soil, water, and air.
