SE 559 Memosens® pH Sensor TEXT SIZE: A A A    PRINT THIS PAGE   EMAIL THIS PAGE

The calibrated annular junction enables precise measurements in media of very low conductivity virtually without influence of flow. The large contact surface 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 impossible for a longer period of time.

SE 559 Memosens® pH Sensor

For uncomplicated measurement in ultrapure water, water, and analytical chemistry, digital, with Memosens® technology.
