There are three calibration tables that can correctly view soil problems, easily adjust soil moist, pH or light to plant suitable plants.
Important Tips: 1, Do not touch the stone or hard rock soil, if the soil is too hard and dry, easy to damage the probes. 2. Design for testing soil ONLY. 3. After using, need to clean and wipe the probes.
When measuring soil pH and humidity, left 1cm of probe to avoid destroying electrode.
