Hamilton IonoTrode pH Electrode for Low-Conductivity Media

The Hamilton IonoTrode is a pH electrode for ion-weak media with very low conductivity. It is not an ion-selective electrode: it measures pH, not a specific ion. Its F glass membrane has a very low resistance, so the sensor gives stable measurements in samples with a conductivity of at least 0.2 µS/cm. As one of Hamilton’s distributors in Turkey, Mikron Proses (Üsküdar, Istanbul) supplies IonoTrode electrodes and provides application consulting on sensor selection.

Sleeve diaphragm and side-arm

If a storage container with 3 M KCl is attached through a tube to the side-arm of the IonoTrode, the outflow of the electrolyte can be controlled with the PTFE sleeve diaphragm ring. The sleeve is removable, which allows the electrolyte outflow to be checked.

Key features

Feature	Specification	Benefit
F glass membrane	Very low resistance	Stable measurement in samples down to 0.2 µS/cm
PTFE sleeve diaphragm	Removable ring	Control and checking of the electrolyte outflow
Side-arm	Tube to a 3 M KCl reservoir	Pressurization through the side-arm and electrolyte supply from an external vessel
