Anyone who wants long-term success growing plants in a grow tent can't avoid the subject of pH & EC meters. Only by regularly measuring and checking the pH value and EC value of your nutrient solution can you ensure your plants always have optimal conditions. Whether with an Aqua Master, a classic pH meter or a digital EC meter – precise measurements are crucial for maximizing yields and avoiding problems such as nutrient deficiency or overfeeding.
pH determines whether your plants can take up the nutrients you give them, and EC tells you how strong your solution is. This collection covers pH, EC and combo meters from Aqua Master Tools, including the P50 Pro, E50 Pro and P700, handheld and substrate meters, plus Platinum pH and EC meters. You'll also find calibration solutions, Cleaner D, KCl storage solution and spare probes. Choose a pen for quick tank checks, a combo meter if you want several values in one, and a substrate meter to measure in the root zone. Read why accurate pH and EC matters, see the Aqua Master Tools range and adjust with nutrients.
