Features:\nBattery is no need.\nCould test soil pH soil fertility\nSuggest to use indoors or outdoors\nconvenient to use, simple to operate, solid quality\nAccurate results\n\nSpecifications: \nMaterial: Plastic\nSoil PH Measurement Range: About 3.0 - 10.0 pH\nAccuracy: About ±0.25 pH(20℃)±0.2 pH (Suitable for farm or education experiments)\nSoil Moisture Test Range: About 0-10\nWorking Temperature: About 0 - 50°C(32-122°F)\nCalibration: Manual point 1\nMeasurements: About 27cm/10.63" X 5.5cm/2.17"\nLength of Probe: About 18cm/7.09"\n\nNotes: \n1. Soil pH value is a very important factor for the quality of crops. \n2. Most of crops cannot survive in too or too alkaline soil.\n3. Get the right pH reading for your Crop is very important.\n\nUsing Method:\n1. Measuring soil pH and moisture, as far as possible to probe deeply into the earth and probe the upper portion for about 1 cm.\n2. On the table is 2.5-9 numerical, numerical 7 basic is neutral, the smaller the number shows that the greater the ity, please adjust soil pH value according to plant varieties.\n4. Please pay attention that insert electrodes without touching the stone, not too hard, otherwise easy to damage the electrode, clean electrode after use.
