Dissolved oxygen meter SevenExcellence S900 / S600
The model S900 offers a bench-top solution with OptiOxä technology: the optical measurement of dissolved oxygen. Thanks to OptiOxä, measuring dissolved oxygen is easier than ever before. For applications where the traditional polarographic measurement is preferred the S600-Kit is recommended. Optical oxygen measurement is superior to conventional technologies. OptiOxä is fast, precise and produces highly reproducible results. Because of the optical measuring principle used, the oxygen is not chemically consumed during the measurement, which makes stirring the sample superfluous. The InLab OptiOxä requires no polarization time, meaning you can start your measurement immediately. In addition, the whole measuring system has a high level of stability making calibration rarely necessary.
