Easy to use, each soil moisture meter reads in a scale of “1” to “10,” with “1” being completely dry and “10” indicating full saturation. To use, insert brass probe into soil. Sensing element is located in the tip of probe. A chart on the back of each unit indicates relative moisture readings. To calibrate, simply adjust meter to any soil type.
Complete instructions, Soil Moisture Management Handbook, and wilt point tables for various plants are included. All meters operate on one AA battery (included).
