    ScienceLine – The proven high-end laboratory electrodes

    In research and development, manufacturing and quality control, our ScienceLine electrodes have become standard for the most demanding measurement tasks. Each electrode has an individual serial number and pH metal combination electrodes are supplied with a quality certificate, better making documentation simple and better traceable. We have kept on improving the glass membrane shapes and types to make the electrodes even more robust, durable and easier to clean. Furthermore, they achieve stable measurement values even faster.
