The soil NPK sensor is a high functional and digital display soil meter, it can quickly test nitrogen phosphorus potassium of different kinds of soil.
The soil NPK meter is precision, quick, stable, wide range, display clear, portable and easy to test.
The soil nitrogen, phosphorus and potassium sensor is suitable for the detection of the content of nitrogen, phosphorus and potassium in the soil.
The fertility of the soil is judged by the detection of the content of nitrogen, phosphorus and potassium in the soil, thus facilitating the evaluation of the soil situation by the customer system.
Sensors are suitable for all kinds of soil, can be long-term embedded in the soil, long-term resistance to electrolysis, corrosion resistance, vacuum irrigation, completely waterproof
Measure the surface of the soil or be buried in the ground for a long time, resistant to long-term electrolysis, corrosion resistance, completely waterproof.
High measurement accuracy and long-term stability of signal. Widely used in agricultural irrigation, greenhouse, grassland, environmental monitoring, water saving, soil test.
