1. The probe should be in full contact with the soil and compacted to ensure the accuracy of the data.
2. Soil tachometer only tests soil and soil. It is not suitable for dry flour, small stones, organic wood chips, liquid particles, etc.
3. The closeness of the soil will directly affect the measurement value and cause errors. In order to improve the accuracy of the test results, please use the method of multi-point test to take the average value.
4. When using, pay attention to the test point not to touch the stone, do not force too hard, otherwise it is easy to hurt the needle. Should not be inserted in the soil for a long time, easy to oxidize.
5. After the measurement, clean the soil particles on the surface of the probe with gauze in time to keep the probe dry.
6. The soil npk tester  is directly inserted into the dry and hard soil, which will not read the correct concentration of NPK at the measurement point due to low ion activity, and the dry and hard soil will cause damage to the probe. It is not recommended to use the speed meter to measure the dry and hard soil.
7. When measuring NPK concentration, first pour pure water or distilled water into the measured area at least 10cm deep, and then insert the steel needle into the wet soil to make the steel needle contact the soil easily and evenly. Press the button to read the concentration of NPK at the measuring point according to the operation.
8. When the speedometer is not in use, do not rub the probe surface or scratch it directly by hand, and keep it clean and dry, away from magnetic objects and other metal objects.


1. How to use a soil npk tester?

At the place to be measured, insert the sensor alloy probe vertically into the soil and press the button to begin the measurement.

After pressing the button, power on for 1 second, and then test for 2 seconds. The multi-element model displays each element for 3 seconds, and the screen displays three times. If it is a single element model, the test results will be displayed for 10 seconds, and then the screen will stop. If the button is pressed again during the display, it will recheck for two seconds and loop the display again.

2. How do I replace the battery?
