SE 559 Memosens pH Sensor


Low-maintenance pH sensors with gel reference electrolyte The annular junction enables precise measurements in media of very low conductivity without influence of flow. The large contact surface area of the junction minimizes problems caused by contamination. The sensor is ideal for processes for which liquid-electrolyte sensors should be used, but where maintenance is difficult for long periods of
