What is the shelf life of my pH or ORP sensors?
pH/ORP sensors and storage details
We do not recommend to store the pH or ORP sensors if at all possible. If storage is necessary, please keep the storage time to a minimum (2-4 weeks) . Please be sure to store the probe with the storage cap on and the storage cap sponge wetted with a 4 or 7 pH buffer. Every 2 to 4 weeks check on the probe to rewet the sponge to prevent the sensor from drying out. If a sensor that comes out of storage is not reading correctly, it is recommend to soak it in a 4 buffer overnight to try to reactivate the salt bridge.
