Double Junction Reference Probe
This is a reference electrode designed to be used in a Waspmote wireless sensor platform by plugging it into the Waspmote Smart Water Ions Sensor Board.
This probe is required when using the Bromide Ion, Chloride Ion, Cupric Ion, Iodide Ion, Lead Ion, and/or Silver Ion sensors — up to four in any combination. The pH Sensor also can be used while this reference probe and up to three of those ion sensors are attached.
Connect this probe to the REFERENCE port on your Smart Water Ions Sensor Board. It will provide a stable and well-known electrode potential. This is critical to acquiring good electrochemical data. Drift in the reference electrode potential can cause quantitative and qualitative errors in data collection and analysis beyond simple inaccuracies in the measured potential.
