Horiba pH Electrode 3-in-1 Plastic Body Hydrofluoric Acid

Horiba pH Electrode 3-in-1 Plastic Body Hydrofluoric Acid Resistant Type – Ceramic Liquid Junction (Model 9631-10D)

Horiba 9631-10D is a 3-in-1 combination pH electrode specifically designed for pH measurement in samples containing hydrofluoric acid (HF) and other aggressive chemical solutions. This Hydrofluoric Acid Resistant type electrode integrates the pH sensing element, reference electrode, and temperature sensor into a single probe, enabling automatic temperature-compensated (ATC) pH measurement when used with compatible Horiba meters.

Unlike conventional glass electrodes that can be damaged by HF, the plastic body construction of the 9631-10D provides enhanced chemical resistance, making it suitable for laboratory and industrial environments where hydrofluoric acid is handled. The ceramic liquid junction ensures stable electrolyte flow and a reliable reference potential, supporting consistent and reproducible pH measurements even in chemically harsh conditions.
