A handheld soil tester with one probe. It reads soil pH, moisture and temperature, and the light level where it stands.
Push the probe straight down into the soil, away from plant stems, and switch on. A switch on the back selects pH or moisture; soil temperature shows with the moisture reading, in °C or °F. Point the light window at the light for a light reading. Take several readings. If the soil is too dry for a pH reading, wet it and test again after half an hour.
It takes one 9 V battery, not included. Keep the protective sleeve on the probe when it's not in use.
