TPY-6A Soil(fertilizer) nutrient tester

TPY-6A

In addition to testing N, P, K, acidity, alkalinity, organic matter, salt content function, but also can output fertilization guidance formula, for the guidance of agricultural production to bring convenience, with host storage function, printing function, AC and DC dual-use, can be in the field directly out of the results, directly to the land site soil testing and according to the needs of the formula.

TPY-6PC

With all the functions of TPY-6A, it can be connected to a computer to distribute fertilizers and print out the formulated fertilizer table.

TPY-7PC

In addition to all the functions of TPY-6A, a soil moisture sensor can be added, seven parameters can be detected at the same time, and can be connected to a computer through the computer to allocate fertilizer and print out the formula of fertilizer table, an instrument with multiple functions.
