Ionode

Established in 1972, Ionode is a specialist manufacturer of pH, ORP and ion selective electrodes for industrial, field and laboratory applications. An industry leader in technical innovation, Ionode has developed many manufacturing advances including our unique automated glass blowing process and reference element fabrication. We set the standard in the manufacture of reliable, quality products. TECHNOLOGY AND INNOVATION Our automated glassblowing machines allow us to easily make a variety of different pH membrane shapes, including more complex styles such as spear and bullet membranes. The process uses a uniform mass of pH glass to ensure a consistent, reliable product. Other innovations include the integration of the electrode barrels and caps (making them submersible) and advances in integral temperature compensation and multi-parameter sensor design.
