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.

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

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

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

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

l         Chinese big-screen LCD shows, and will guide you how to operate.

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

l         Armor plate shell, firm, beautiful and durable.

l         According to the local situation, you can set the variety, productivity, kind of fertilizer and will automatically calculate the fertilizing amount.

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