The particularly rugged and reliable standard pH combination electrodes are intended for any test, production or teaching laboratory. They are ideal for routine measurements in large-mouthed recipients (beaker, Erlenmeyer flask, etc.), offering excellent response times. Used mainly in industrial, pharmaceutical and medical research, the pH MICRO electrodes are designed for small recipients or apparatus with a small volume of the specimen (haemolysis tube, NMR tube, electrophoresis plate, column outlet, etc.). Combination electrodes Shape of glass electrode Electrode body Pointed reinforced Recommended...

Measurement of redox potential Redox potential is a measurement in millivolts (mV) for qualifying an aqueous solution and classify it as oxidizing or reducing. This measurement can be performed with a pH-meter measuring the mV and a metal electrode dedicated to redox potential measurements. A redox potential sensor comprises a reference electrode made up of a silver wire and a measuring electrode made up of a platinum or gold wire. The measured potential value E depends on the ion concentration, the pressure of the gases present and, if relevant, the pH when H+ ions are involved in a pair. Redox...

Conductivity cells & temperature sensors Electrical conductivity is the capability of a solution, metal or gas to allow an electric current to flow through it. In a solution, it is the anions (- charge) and cations (+ charge) which transport the current, whereas in a metal, it is the electrons. Conductivity is measured by applying an alternating current to a measuring cell. This cell is composed of a glass body supporting two to four platinum plates (also called poles) immersed in a solution. Like pH, conductivity measurements depend significantly on the temperature. When the temperature of a...

Dissolved oxygen measurement These rugged PVC dissolved oxygen probes are based on the principle of the Clark probe and can be used in a temperature range from 0° to 60°C. The oxygen-permeable membrane is mounted on a washer (BO23 and BOT2). The assembly, maintained by the removable protective end-piece, is very easy to change. A temperature sensor is associated with the dissolved oxygen probe (BOT2 and BOT4) to enable automatic temperature correction. Dissolved oxygen probes Measurement range Electrode body Clark probe Temperature sensor Operating temperature Ø and length under cap (mm) Cable...
