Hydrolab

ORP

The state of the reaction is measured by the potential developed between and inert noble metal electrode (platinum) and a reference electrode (same reference for pH)

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
