Product Description

Our Ion-Selective Electrodes (ISEs) are double junction combination electrodes and do not require an external reference electrode.  

This electrode gives a good indication of hardness of water (as Ca2+). It is also used as an endpoint indicator in EDTA-Ca/Mg hardwater titrations.

Electrodes are combination-style, non-refillable, and gel-filled.

It is important for you to know that Forston ISE membranes, like all other PVC ISE membranes, have a limited life expectancy; however, the replaceable module of Forston ISEs allows you to simply discard the used one, and replace it with a new module. We recommend that you do not purchase replacement modules far in advance of their expected time of use, as their life expectancy is limited as well.

Two calibration standards and a short-term soaking bottle are included.
