YIERYI 2 in 1 Professional Digital Soil EC/Temperature Tester

Instructions:1. Remove the electrode protective cover. 2. Press the power button to turn on.3. Insert the electrode into the corresponding depth of the soil to be tested, if necessary, add an appropriate amount of deionized water.4. Stand still and wait for the value to be read.5. Press TEMP to switch ℃/℉.6. After use, press the power button to shut down, clean the electrode to reduce pollution and save.Calibration method:1. Put the long electrode into the 1.41mS standard solution after starting up, shake it gently, and wait for the value to stabilize.2. Long press the CAL button to display CAL, the value flashes to enter the calibration mode, press ▼ to decrease the value, press ▲ to increase the value, adjust the value to 1.41mS, the value flashes, the calibration is successful. What is the soil EC value? The soil EC value is the soil electrical conductivity, and the soil electrical conductivity is an index for determining the water-soluble salt of the soil. Water-soluble soil salt
