Horiba pH Electrode Combination Glass Body ToupH Micro

Horiba pH Electrode Combination Glass Body ToupH Micro Type – Ceramic Liquid Junction (Model 9418-10C)

Horiba 9418-10C is a combination pH electrode designed for accurate and stable pH measurement in small-volume and micro-sample applications. This ToupH Micro type electrode combines the pH sensing glass membrane and reference electrode into a single compact probe and is intended for use without an integrated temperature sensor, making it suitable for systems employing external temperature compensation or measurements conducted at controlled temperatures.

The electrode features a slim glass body optimized for precise positioning in narrow containers, test tubes, cuvettes, and small beakers where standard-size electrodes are impractical. Its ceramic liquid junction provides controlled electrolyte diffusion and a stable reference potential, ensuring reliable and reproducible pH readings even when working with limited sample volumes.
