Soil Fertilizer Nutrient Tester, AC Mains: 220V to 240V, 50Hz, Test Range: 0.01% to 1.00%, Linearity Error: Less Than 3.0%

Detect on availability on Nitrogen, Phosphorus, Potassium, Organic matter, Total Nitrogen, Total Phosphorus, Total Potassium in Plants, 73 Types of Instrument Memory The nutrients needed for the growth and development of crops can be directly applied to the fertilizer on the local machine and the amount of fertilizer output can be output without printing function, including storage batteries, AC and DC. 

Functional characteristics:

1. It can detect available nitrogen, available phosphorus, available potassium, organic matter content in soil, plant, chemical fertilizer, biological fertilizer, etc., soil pH, soil salt content, total nitrogen, total phosphorus, total 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. Select fertilizer varieties and crop varieties on the host computer, input the target yield, and automatically calculate the recommended fertilizer amount. 

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

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

7. There is a look-back function in the test process, thus making the product more convenient and reasonable (with backlight function, able to adapt to night use). 

8. 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.
