pH and Conductivity Solutions
pH and conductivity solutions are must-haves to keep your pH and PPM meters running accurately and to prolong their life. Conductivity meters typically won't need much, just a calibration solution to check and recalibrate as needed. With a pH pen you'll need a storage solution as well as pH 4 and 7 solutions for precise calibration. We also recommend a cleaning solution or cleaning kit for both, especially the pH meter.
