Step 4: Attach Dowels and Drill Holes in the Body of the pHloat
Next drill a small hole into the pHloat. Do not do this in the center. After the hole has been drilled, pull a small piece of rope (approximately 6’ in length) through the hole and tie a knot. This will allow for the pHloat to be retrieved easily.
7. Next take your plastic container and drill two holes in the bottom of the container spread about 1” apart. The holes should be about the same diameter as the legs of the pH sensor found in the kit.
