Gardeners can conveniently test their moisture, light, and pH levels with the handy ActiveAir 3-Way Meter. Moisture readings register on a scale of 0 (dry) to 10 (moist), light readings range from 0 (low light) to 2000 (very strong light), and pH readings between pH 0 (acidic) and pH 10 (basic) are represented.
The durable, easy-to-read tester is suitable for indoors or out and needs no batteries to operate.
DO NOT LEAVE IN SOIL. CLEAN PRONGS AFTER EACH USE.
