Before using the tester, be sure to thoroughly clean its metallic surface with a piece of whetting cloth. When using a brand-new tester, we advise you to insert it into the soil a few times before taking your reading. This is in order to remove any oily impurities from its metallic surface that may affect the accuracy of your soil pH or moisture reading. Insert the meter directly into the soil that requires testing, embedding its metallic surface completely and tamp down the surrounding soil so that is adheres closely to the meter's metallic electrode surface. About ten minutes after inserting the meter in the soil, the pointer will indicate the correct value of pH or moisture. The meter may sometimes register different values depending on the oil surface, moisture content etc. Therefore it is advised you take an average of several measurements. Press the white button and the pointer will indicate the correct moisture value. After use, wipe all the soil or moisture off of the metallic surface. à¤Ã×èͧÁ×ÍÇÔ·ÂÒÈÒʵÃì ÍØ»¡Ã³ìÇÔ·ÂÒÈÒʵÃì Moisture Meter Moisture Meter à¤Ã×èͧÇÑ´¤ÇÒÁª×é¹ pH Meter ¡Ã´´èÒ§¢Í§´Ô¹ CMT-0217
