Horiba pH Electrode 3-in-1 Needle Type

Horiba pH Electrode 3-in-1 Needle Type – Ceramic Liquid Junction (Model 6252-10D)

Horiba 6252-10D is a 3-in-1 combination pH electrode designed for direct pH measurement in semi-solid, soft solid, and low-moisture samples. This needle-type electrode integrates the pH sensing glass membrane, reference electrode, and temperature sensor into a single slim probe, allowing accurate and temperature-compensated pH measurement when used with compatible Horiba meters.

The needle-shaped tip enables direct insertion into samples such as food products, gels, pastes, soil, biological materials, and other non-liquid matrices where conventional bulb-type electrodes cannot be used effectively. The ceramic liquid junction provides stable electrolyte flow and a reliable reference potential, ensuring consistent and reproducible measurements.

Key Features
