Horiba pH Electrode Combination Glass Body Flat Type

Horiba pH Electrode Combination Glass Body Flat Type – Sleeve Liquid Junction (Model 6261-10C)

Horiba 6261-10C is a combination pH electrode designed for accurate and stable pH measurement on flat surfaces and shallow samples. This Flat type electrode combines the pH sensing glass membrane and reference electrode into a single probe and is manufactured without an integrated temperature sensor, making it suitable for applications that use external temperature compensation or operate under controlled temperature conditions.

The electrode features a flat glass sensing surface, allowing direct contact measurement on solid, semi-solid, or thin liquid samples where conventional bulb-type electrodes cannot provide reliable results. Its sleeve liquid junction offers a wide contact area between the reference electrolyte and the sample, improving measurement stability and reducing clogging when measuring samples containing particulates or viscous components.

Key Features

• Combination pH electrode (pH sensor + reference electrode)
