The perfect solution to store and hydrate your Bluelab pH products.
pH probes are sensitive glass instruments which age through normal use. The life and performance of pH probes is reduced heavily when they are used or stored dry. Bluelab pH Probe KCl Storage Solution is made specifically for use with Bluelab pH products. It is designed to increase response time and maximize the life of Bluelab pH pens and pH probes. For best results, use the KCl solution to store the pH pen/ probe after use and hydrate monthly. Instructions are on the bottle label.
