Solid State Reference Electrode 12mm NaCl

The E8198 is a unique solid state Reference electrode which requires no maintenance and no filling solutions. The probe is compatible with all pH and Ion Selective electrodes and can be used for lab and field applications including constant immersion.

This probe has a polymer outer body and a crystalline tip surface that slowly leaches NaCl. This provides a stable reading with the appropriate sensing electrode. The tip can be rubbed down to expose a new surface when required.

For applications where Sodium Chloride is not suitable there is an alternative. Please see E8197 which is a KCl equivalent product.

The probe can be left dry when not in use and is ideal for use with ISE half cells which are also solid state and can be left dry.
