Specification: Condition: 100% Brand New Item Type: Soil tester Material: ABS+ aluminum Purpose: Soil tester Length: Approx. 41cm / 16.1in PH Range: 3-8 pH Moisture Range: 1-8%; PH Accuracy: ±0.2pH; Moisture Accuracy: ±1%. Ambient Temperature: 5-50℃. Method of use 1. If the soil at the test point is too dry or too much fertilizer to measure the PH of the soil, splashing water on the test point first and wait for 28 minutes to measure again. 2. Before using the meter, wipe the metal absorption plate with abrasive cloth completely to avoid affecting the measured value.If the new product is not used, the metal plate has protective oil on the surface, must be inserted into the soil several times, after grinding to protect the oil layer before use. 3. When the acid base value is measured, directly insert it into the soil at the test point, and the metal plate surface must be all put into the soil. T he correct value can be obtained in about 10 minutes.The density, humidity, and excess fertilizer of the soil may affect the values, so several measurements must be made at different locations to obtain averages. 4. The PH value of the tester is stable after 10 minutes, then press the white button on the side and the humidity will be displayed immediately.. Package List: 1 x Soil tester Note: 1. For the first use, insert the probe into the soil several times to remove the oil and impurities. When measuring the pH and humidity of the soil, first insert the probe as deep as possible into the soil. After about 10 minutes, read the pH value and press the white button besides it.2. Be careful not to touches the stone when inserting the electrode. Do not exert too much force, otherwise it will easily hurt the electrode.Do not place the instrument with the magnetic material, and do not leave it in the soil for more than an hour.Wash the electrodes after use.3.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
