Routine pH electrodes

These InLab® electrodes cover most laboratory applications in aqueous samples. Due to ARGENTHAL®-lead off system and silver ion scavenger, a contamination by sulfide-containing media is excluded and an improved temperature stability can be attained. This ensures that the electrolyte is completely free of silver ions and therefore also suitable for biological specimens.

Professional pH electrodes

With their open connection, the electrodes are especially unsusceptible to contaminations. The polymer reference electrode on these sensors is in direct contact with the measurement medium, therefore the diaphragm cannot clog. The PEEK-shaft is extremely resistant both chemically and mechanically.

pH expert electrodes

Extreme specialist or top generalist - these electrodes are either one or the other. Here, you can find special electrodes for small, cold samples containing hydrofluoric acid and pure, viscous and very adherent samples. The puncture electrode InLab®Solids was designed for ph-measurement for foods such as fruit, cheese or meat. The InLab®Surface was developed for ph-measurement of surfaces, e.g. paper or skin. It is also perfectly suitable for determining drop-sized samples on a glass carrier.
