EC Calibration Solution

If you use an EC meter to accurately measure the strength of your nutrient solution, you will need to calibrate it from time to time to ensure its accuracy and the easiest way to do this is with some EC Calibration Solution, which is a fixed and known solution of 2.76 EC for calibrating your meter.


How To Use
Pour out a small amount of EC Calibration Solution into a cup or beaker, just enough to cover the probe. Dip the meter into the solution and press the calibrate button on your meter to calibrate it to 2.76 EC and when finished discard the used calibration solution.
