Water Master EC 1413 Conductivity Solution (300ml)

EC is one of the most important values in cultivation: it reflects the salt and nutrient concentration in your solution, so having your pH and EC meters well calibrated is key to not overdoing or underdoing your feeding. The Water Master conductivity solution sets the standard of 1413 µS/cm (at 25°C), and in its 300 ml bottle works out more economical than sachets.

How to calibrate

Pour into a separate container the amount you need, insert the probe and adjust the reading to 1413 µS/cm. It's a single-use solution: discard any leftover and don't return it to the bottle, so you don't contaminate it. Keep the container tightly sealed and in a cool place.

Also calibrate the pH

Complete control of your nutrient solution means monitoring both EC and pH at the same time. For pH, combine it with the pH 7.01 calibration solution from the same range.
