Specifications: PH range: 2.5-9 PH PH Accuracy: ±0.5PH Ambient temperature: 5-50 degree centigrade Weight: 200g Size:11cm*6cm*3cm How to Use it When using for the first time, 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 into the soil as deep as possible, and read the PH value after about 10 minutes. When using it, be careful not to touch the stone when inserting the electrode. Do not use too much force, otherwise it will damage the electrode. Do not put the instrument and magnetic material together. Do not keep it in the soil for more than 1 hour. Wash the electrode after use. Package Included: 1 *Soil PH Detector Note: 1. If the soil at the measuring point is too dry or the fertilizer is too much to measure the pH of the soil, first splash the water at the measuring point and wait 30 minutes before measuring. 2. Before using the measuring device, use a grinding cloth to completely wipe the metal absorption plate to prevent the measured value. The surface of the metal plate has protective oil.In order to removed the protective oil layer you should insert it into the soil several times before use it. 3. When the pH value is measured, it is directly inserted into the soil of the test point, and the surface of the non-ferrous metal must be completely filled into the soil. You will get the correct value in about 10 minutes. Soil density, humidity, and excessive fertilizer may affect the measured value, so it must be measured several times at different locations to average.
