These galvanic sensors are ready-to-use and are equipped with protective hoods for rough conditions.

CellOx* sensors are membrane-covered and waterproof. The membrane can be used for up to six months. Sensor also features high signal resolution, temperature compensation, rapid response, and membrane leakage monitoring. Includes a waterproof plug.

DurOx* oxygen sensors are membrane-covered and waterproof. Use for up to six months with only one electrolyte filling. Features temperature compensation and low approach flow. Includes a waterproof plug.

The StirrOx* self-stirring oxygen sensor simultaneously stirs and measures oxygen in Karlsruhe bottles and Winkler bottles. Sensor uses a constant approach flow for high reproducibility, consumes a very low amount of oxygen, only 0.008 µg h^-1 (mg/l)^-1, and features temperature compensation. Single-handed operation allows for rapid series measurements.

The SenTix* pH electrode features optimized membrane glass that guarantees quick measurement, even at low temperature.

Simple air calibration can be achieved by using a calibration vessel.
