The electronic digital display 4-in-1 soil analyzer is the latest soil rapid measuring device. It mainly tests soil acidity, alkalinity, moisture, temperature and plant light intensity. It uses a 9V carbon battery with a simple probe length of 200 mm. The instrument measures parameters through liquid crystal display(LCD). This instrument also has the function of low power indication and automatic power disconnection. It saves time and energy and efficiency. This instrument is suitable for planting flowers and grass and landscaping.
Functional characteristics:
1. Measure the intensity of the current environment.
2. Measuring soil moisture content.
3. Measure the temperature of soil. The range of temperature measurement is -9~+50℃(16~122℉),precision 1℃/1℉
4. Measuring soil pH, PH measurement range: 4.0-9.0
Working temperature: +5℃~+40℃
PH measurement range: 4.0-9.0
Size: 81*350*40mm/3.19*13.78*1.57″
Probe length: 200mm/7.87″
Weight: 200 g 
Power supply: 9V battery (not included)
Usage method:
Please install the battery before use, remove the probe protective sleeve.
1. Illumination measurement
A. press ON button to turn on the instrument.
B. aligns the highest point light source sensor window.
C. current intensity of light will be displayed in LCD.
Note: please do not block light or create shadows for light sensors.
2. PH range measurement
A. pushes the PH/ button on the back to the location of PH.
B. inserts the probe vertically into the soil and needs to be tested as soon as possible.
C. press the ON button to start the measurement.
D. The pH value of the test will be displayed on the LCD screen.
E. measured several times to get the exact value.
Be careful:
Vertically insert the probe at the edge of the plant stem in the middle.
Please gently push into the soil to avoid damaging the probe.
If the measured soil is too dry or fertile to measure the exact PH value, the user can sprinkle some water and measure it again in half an hour.
3. Moisture measurement
A. pushes the PH/ button on the back to the temperature.
B. vertical insertion into soil as far as possible.
C. press the NO button to start the measurement.
D.The soil humidity of the test will be displayed on the LCD screen.
4. temperature measurement;
A. when the humidity is measured, the soil temperature will be displayed on the LCD screen.
B. press the (℃/℉ OFF)button to set the humidity indicator at temperature or temperature. Note: If the user does not insert the probe into the soil, it will show the exact temperature of the external space environment.

Regulation of soil pH: 
1. Lime is often used for improvement of acidic soils. In order to neutralize active acid, latent acid and improve soil structure, purple shale powder, fly ash and grass ash can also be used. 
2. Artificial acidified open-field flowers in neutral and calcareous soils can use sulfur powder (50g/m2) or ferrous sulfate (150g/m2), which can reduce 0.5-1 pH unit. It can also be poured with alum fertilizer. 
3. Applying gypsum to alkaline soil, phosphogypsum, ferrous sulfate, sulfur powder and acid weathered coal can also be used.
1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
2. Please allow slight measuring deviation due to manual measurement.

  1. D***v

    Works, use a new battery, otherwise it is possible not to correct readings

  2. B***v

    Everything works, even like a ph shows well, you need to still test but it seems like it's normal.

  14. M***a

    Thank you very much to the seller! So quickly the order was not delivered to me once. The device received a whole, working, although the packaging, you can say, no. Thin cardboard box wrapped in film. The device works, but it is still unclear how. According to his testimony, my garden plot is located on the acid swamp. Even in the rotten manure heap of ph no more than 5,6.

  15. R***r

    Very large measurement of ph in 0,5. And so all the norms.

  16. Y***v

    It's okay.

  17. R***a

    The product works. It has inside a piece of plastic loose on the screen, which does not affect its use. Temperature readings are slow but accurate, ph readings are estimated to be 0.5 closest
