HydroFarm, Active Air 2-Way Meter

• No batteries needed
• Prevents overwatering and underwatering
• Determines accurate pH values from 4-8
• For indoor and outdoor use
• Sturdy design for long-term usage
• If you are checking for pH you will need some distilled water to mix with the soil before taking a reading, so youll want to pick up some before your Active Air 2-Way Moisture/pH Meter arrives.

Gardeners can conveniently test moisture and pH levels with the handy Active Air 2-Way Meter. Moisture readings register on a scale of 0 (dry) to 10 (moist). pH readings between pH 3 (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. Remove from soil and clean prongs after each use to ensure the moisture meter stays in top performance shape.
