For efficiency and longevity, we recommend that you clean and maintain your pH and conductivity probes on a regular basis. For conductivity, use Bluelab 2.77 EC Conductivity Standa rd Solution whenever you clean your conductivity probe to test whether cleaning has been successful. While no calibration is required for conductivity, you will need to calibrate your pH probe. This easy-to-follow calibration process is the same for all Bluelab pH products. After cleaning your pH probe, simply calibrate it with pH calibration solutions at two reference standards - 4.0 and 7.0 pH. In addition, you should hydrate and store your pH probe using Bluelab KCl Storage Solution. Show more
