Burkert Fluid Control Systems introduces its new pH electrodes. This pH electrode consists not of glass but durable enamelled stainless steel. This allows it to be used in applications in which the liquid being measured contains solids. The pH electrode was conceived for the exacting demands of the food and beverage industry, pharmaceutical and chemical applications and also in water and sewage treatment. The new pH probe can be sterilised in-line, and therefore does not have to be removed from the pipeline during a cleaning cycle.
