AMT - Model T -Galvanic Oxygen Micro-Sensor
The galvanic O2 micro-sensor has been developed for the insitu determination of oxygen containing aqueous solution. Therefore the sensor is suitable for direct measurements in lakes, estuarines, rivers, oceans and sediments. Compared with all the other commercially available oxygen sensors this galvanic oxygen micro-sensor works with such a low analyte consumption, that streaming of the sensor membrane or stirring of the analyte is not necessary. Therefore an additional stirrer is not necessary for stationary measurements
The second main difference to other DO sensors is the very fast response time of the galvanic oxygen micro-sensor produced by AMT with t90% down to 200 milliseconds compared with approximately 6 to 20 seconds in the case of the conventional sensors. The third advantage of the new micro-sensor is founded in the micro-sensor technology. Galvanic oxygen micro-sensors are working with a high local resolution and allow profiling with μm-steps. Therefore also measurements in soft sediments or mud became practicable.
