Replacement Reference Electrode For ISFET Meters

ISFET Reference electrodes have a finite lifetime caused by reference junction blockage or loss of electrolyte. The S2K333/REF is a replacement reference electrode for an ISFET Meter. A replacement should be made when calibration becomes impossible or results become sluggish.

Simply pull out the old electrode and replace it. The black O-ring seal will ensure that the unit will retain its water resistance to IP67 standard.

Remove the red dot from the ceramic tip for operation. The Reference Junction is close to the Chip sensor on the meter which allows measurement of small volumes as low as 1 drop.

After use place the protective cap back on the ISFET Meter.
