Horiba pH Electrode Combination Plastic Body Standard Type

Horiba pH Electrode Combination Plastic Body Standard Type – Ceramic Liquid Junction (Model 9425-10C)

Horiba 9425-10C is a combination pH electrode designed for accurate and stable pH measurement in routine laboratory and field applications. This Standard 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 use with external temperature compensation or measurements performed at controlled temperatures.

The electrode features a durable plastic body, offering improved resistance to breakage compared to glass-body electrodes and making it ideal for frequent handling, educational environments, and portable testing. Its ceramic liquid junction provides controlled electrolyte diffusion and a stable reference potential, ensuring consistent and reproducible pH readings across a wide range of aqueous samples.
