measurements of dissolved oxygen


  • Rapid measurements of dissolved oxygen.
  • Ideal for solutions with depths less than 1m.
  • Data loggers are available if required.

This laboratory version of the galvanic AMT-O2-microsensor has been developed above all for the very fast measurement of dissolved oxygen. The sensor has very short response times and streaming as it is well known from nearly all kind of Clark-type oxygen sensors is not necessary. So profiling and stationary measurements without stirring the analyte become possible with very high signal and local resolution.

The sensor is ready for use immediately without any polarization or warm-up time. The sensor includes an integrated electronic device for the transformation of the sensor current into a voltage of 0...+ 3 V (DC) and an exchangeable sensor tip. The exchange of the sensor tip is very easy and could be done by the customer himself.

All sensors are delivered with temperature compensation data and with mathematics to calculate the oxygen concentration or the saturation index.
