For accurate EC readings, it’s important to keep the reading equipment clean, in particular the probe. If dirty or contaminated, it will more than likely give an inaccurate reading, meaning your nutrient solution will not be at the optimum for healthy growth and flowering.

By using the Bluelab Conductivity Probe Care Kit, you can confidently, and accurately, clean the all-important probe on meter readers, as this will not only keep it accurate, it will also prolong its overall life.

One question we’re often asked is how do you know if the probe needs cleaning, as a rule of thumb, they should be cleaned around every 30 days, but if readings seem to be significantly lower than usual, there’s a good chance the probe needs a good clean.
