FEATURES

Features:

KCl impregnated glass bulb is permeable to hydrogen ions; reference filled with 3M KCl and has a porous Teflon junction. Salt bridge is formed between the two, and a potential is measured. Choice of standard or integrated refillable reference. Compliant with SM2580 B

Benefits:

Reference electrode is easily refilled in seconds – independent of the pH sensor pH sensor does not need replacement when reference electrode is depleted; simply refill the reference
