Ph Meters

Testing for and maintaining optimal pH levels is essential to keep your plants happy and healthy in hydroponics and aquaponics systems. Our pH and EC meters offer quick and easy methods for testing pH levels, temperatures and EC (nutrient levels) of the nutrient solutions. A Bluelab pH controller can make life even easier, as it automatically adds pH up or down solution as needed.
