Soil Fertilizer Nutrient Tester, AC commercial power: 220V to 240V, 50Hz, Accuracy: ±2%, Shock Resistance: Qualified

Can measure indicators: To test nitrogen, test phosphorus, test potassium, organic matter content, soil acidity and alkalinity, soil salt content, total nitrogen, total phosphorus, and total potassium in the plant, with storage and printing functions, including batteries, AC and DC.

Functional characteristics:

1. It can detect available nitrogen, available phosphorus, available potassium, organic matter content in soil, plants, chemical fertilizers, biological fertilizers, etc., soil pH, soil salt content, total nitrogen, total phosphorus in the plant, Potassium. 

2. With Beijing time display function, it can automatically record and save the test sample time. 

3. The host can store no less than 1000 sets of test data, the data can be read out at any time. 

4. The storage and printing contents include: detection date, test time, test items, sample content, crop varieties, fertilizer varieties, fertilization amount and other related information.

5. Fertilizer varieties and crop varieties can be selected on the host computer, the target output can be input, and the recommended fertilizer amount can be automatically calculated. 

6. Can be arbitrarily adjusted on the host fertilizer utilization. According to different regions, fertilizer adjustment factors and crop fertilization parameters can be arbitrarily adjusted. 

7, bilingual switching between Chinese and English, large-screen LCD display Chinese or English, and guide the operation of each step. 

8, the look-back function during the test, so the product is more convenient and reasonable (with backlighting, can adapt to night use). 

9. Crop varieties, crop yields and fertilizer varieties can be set according to local conditions and the amount of fertilizer (TPY-IV, TPY-6A, TPY-6PC, TPY-7PC) can be calculated automatically. 

10. The results of the tested samples are automatically transferred to a computer for analysis, summarization and preservation. The required nutrients for the growth and development of 73 kinds of crops are stored; the data can be stored by the computer for storage, remote transmission, and printing, and can also be carried out on the host computer without a computer. Soil testing recipes are printed out on a micro-printer (TPY-6PC, TPY-7PC).
