Conductivity standard solutions - a must in every grower's toolbox.
All Bluelab conductivity products must be used with Bluelab 2.77 EC Conductivity Standard Solution. To guarantee your Bluelab products last longer and retain accuracy, all Bluelab solutions are produced especially for Bluelab products and are referred to rigorous laboratory standards.
We advise routine cleaning and testing of your Bluelab conductivity goods if you wish to maintain the items' accuracy.
You won't need to recalibrate any of our conductivity pens or meters because they are all factory-calibrated. Instead, you should clean your Bluelab EC probe and then check to see if cleaning was successful using the Bluelab 2.77 EC Conductivity Standard Solution.
Every 30 days, you should try to clean and test your EC product. Step-by-step instructions for cleaning and caring for each of our items are included.
