Horiba pH Electrode Glass Body ToupH High Viscosity Type

Horiba pH Electrode Combination Glass Body ToupH High Viscosity Type – Movable Sleeve Liquid Junction (Model 9481-10C)

Horiba 9481-10C is a combination pH electrode designed for accurate and stable pH measurement in high-viscosity and difficult samples. This ToupH High Viscosity type electrode combines the pH sensing glass membrane and reference electrode into a single probe and is designed without an integrated temperature sensor, making it suitable for applications using external temperature compensation or measurements conducted at controlled temperatures.

The electrode features a glass body construction for excellent chemical resistance and durability, along with a movable sleeve liquid junction. This junction design provides a large and adjustable contact area between the reference electrolyte and the sample, significantly improving measurement stability in samples that may clog conventional ceramic junctions. As a result, the 9481-10C delivers reliable and reproducible pH readings even in thick, viscous, or particulate-rich media.
