Soil Nutrient Tester

Introduction:

The soil nutrient tester can quickly test the N, P, K, humic acid , organic matter,

salinity, and PH in the soil, fertilizer and plants, and also can store datum, remote send and

print by computer.

1.Quickly test the N, P, K, humic acid , organic matter, salinity, and PH in the soil, fertilizer

and plant

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

3. Store about 1000 groups datum(time, place, fertilizers) , datum can be checked at any time.

4.Print like the test date, number, items, sample contents, variety and so on.

5.Big-screen LCD shows, and will guide you how to operate.

6.When in the test, it has the functions of playback, so it`s very convenient and reasonable.

7.Armor plate shell, firm, beautiful and durable.

8.According to the local situation, you can set the variety, productivity, kind of fertilizer and

will automatically calculate the fertilizing amount.(TPY-6A)

9.The result will automatically transfer to the computer, for analyzing , gathering and

storing(TPY-6PC)
