ION BARRIER – Officially Patented in the United States

2026/02/25

We are proud to announce that ION BARRIER reference technology has officially been granted a United States patent.

This milestone recognises the engineering innovation behind LECOL’s solid-state reference system — specifically designed to enhance performance in harsh industrial environments where conventional liquid or gel references, and even many existing solid-state designs on the market, often struggle.

Unlike traditional designs, ION BARRIER features a controlled ion exchange structure that:

• Minimises electrolyte depletion
• Resists sulphide and heavy metal poisoning
• Reduces dehydration risk at elevated temperatures
• Performs reliably in slurry processes
• Extends sensor service life whilst reducing maintenance frequency

This patent approval validates years of focused development dedicated to solving real-world process challenges.

At LECOL, we remain committed to advancing robust, field-proven measurement solutions for demanding applications across pulp and paper, petrochemical, wastewater, and heavy industry.
