Soil NPK Sensor
The soil NPK sensor is suitable for detecting the content of nitrogen, phosphorus, and potassium in the soil, and judging the fertility of the soil by detecting the content of N, P, and K in the soil. The stainless steel probe of the soil npk sensor can be buried in the soil for a long time and is resistant to long-term electrolysis, salt, and alkali corrosion. The shell is vacuum potted and completely waterproof.
About soil npk sensor
1. Simple to use, few operation steps, fast measurement, no reagents, unlimited detection times.

How to use Portable NPK soil tester:
1. Quick test method
To measure the position, avoid rocks and ensure that the steel needle does not touch hard objects. Discard the top soil at the required measurement depth, keeping the original tightness of the soil below, and insert the sensor vertically into the soil. Don’t rock from side to side. It is recommended to measure the average multiple times in a small area of a measurement point.
2, buried measurement method
Dig a pit with a diameter >20cm vertically, insert the induction needle horizontally into the pit wall to a predetermined depth, and fill the pit tightly. After a period of stabilization, measurements and recordings can be made for days, months, or even longer.
