Aqua Master EC1413 Calibration Solution 100ml - London Grow

Reading the strength and pH of your nutrient formula is absolutely necessary for successful hydroponic growing. It's why you need precise pH & EC meters. Growers use these tools when making up the nutrient solution. Our pH meters are excellent for measuring the alkalinity/acidity of your nutrient formula. They're reliable and offer exceptional value for money. You'll get a digital reading of the pH level of your nutrient formula and adjust accordingly. The devices are made of strong and durable plastic and have an extensive lifespan. They're easy to calibrate and to use. Dip the end of the meter in the nutrient solution and it'll display the pH level of the liquid on the LCD screen. The units are water-resistant.


EC meters allow you to test the nutrient solution's strength to ensure that you feed your crops for optimal development. The meters are accurate, reliable, and cost-effective. You can also save readings. The units are easy to use and to calibrate. Get your nutrient strength accurate for successful growing. Growers worldwide use the pH and EC meters available at London Grow to achieve huge yields and exceptional harvests.
