The EPX-3 electrode is designed for pH measurements on flat humid surfaces of materials like: paper, cardboard, finished leather, fabrics, agar nutrients and also for measurements in water solutions of small volumes.
The electrode has a flat membrane and Teflon o-ring junction placed on 1 plane.
The body material is made of perspex (epoxy) resistant to breakage, aggressive substances and many organic solvents. The electrolyte is not refillable what makes using the electrode easier. High viscosity of the electrolyte prolongs the electrode's lifetime.
The electrode in the standard set is equipped with a glass test-tube of adjusted shape and size, enabling measurements in samples of small volume (above 0.1 ml).
EPX-3 is also delivered with a special elastic pad for measurements of very thin materials and protecting the membrane against mechanical damages.
To keep the membrane active the electrode is delivered with a bottle, filled with KCl, put on its end, which ensures the optimal conditions for electrode storing and continuous readiness for work, it should be taken off before the measurement. Such solution prolongs the electrode's life time. A special sealing ring protects against the electrolyte leakage from the bottle. The ring is tightened by screwing the cap.
High quality at an affordable price.
