The SD pH electrode type 226 with gel electrolyte is not only low-maintenance, but also features fast response times. With the use of two ceramic diaphragms, measurements in water samples with low ionic conductivities are no longer a challenge. The robust plastic housing provides the necessary mechanical stability and protects the cylindrical glass membrane from breakage.
The pH electrode with BNC connection is suitable for all pH meters equipped with a BNC socket. Temperature compensation is achieved either by manual input into the meter or automatically by using a SD temperature sensor.

The spare membrane is ideal for the maintenance of the Oxi 150 polarographic oxygen sensor. Instead of buying a new sensor, it is sufficient to replace the sensor tip at regular intervals.
The service set for the optical oxygen sensor type Oxi L 400 contains a long-life membrane head and a SD card with calibration data as well as a software package for data processing. The calibration data are specifically aligned to the respective luminophore covered membrane. A serial number on both SD card and membrane head helps to check for conformity.
This protective cap is ideal as a counterweight for depth measurements and as protection against mechanical damage.
The service set is ideal for maintenance and care of the galvanic oxygen sensor type Oxi 310. The set contains three replacement membranes with protective caps as well as a 100 ml KOH refill electrolyte in a practical dropper bottle.
This protective cap is ideal as a counterweight for depth measurements and as protection against mechanical damage.
