he rapid measuring instrument is a rapid determination of the content of available nitrogen (N), phosphorus (P) and potassium (K) in the soil by using the principle of electrochemical method and the reduction of the isolation effect.
Details:
1. Remove the sheath cap from the metal probe before using the test.
2. Press the button OFF/ON to turn on the power supply, and the instrument shows the state of zero.
3.① Rapid measurement method: First, the tested soil measurement point is watered with mineral water to a depth of at least 10CM (the best humidity is 70%-80%), and then the metal probe of the instrument is inserted vertically and clockwise into the wet soil at a depth of 6-8 cm, so that the soil and the metal surface of the probe are easily and evenly contacted. The response time is about 10 seconds, and the number shown by the instrument is about 10 seconds. Is the actual measured value. Soil compactness will directly affect the error of the measurement value, so it is required to carry out multi-point measurements as above at different measurement point locations to achieve the average value.
② Precision measurement method: first, the dry soil (or air dried soil) and mineral water (or pure water) according to the ratio of 3:1, put into the container to adjust into a uniform paste state, and then the metal probe of the instrument is vertically inserted into the 6-8CM depth of the container in the soil, about the response time of 10 seconds, the number displayed by the instrument, is the actual measurement value.
4. After each measurement, immediately clean the surface of the metal probe with tissue paper or grinding cloth (cleaning cloth) until the instrument returns to the state of showing zero value.
