Product Description
Shallow Water Micro-sensor for Dissolved Ozone
For very fast depth profiling with probe systems
The amperometric micro-sensor for shallow water has been developed for the fast insitu determinations of dissolved ozone with probe systems in natural waters, industry waters and oceans. Because of the partial pressure of the gaseous O3 , the analyte is separated by permeation through the membrane. Inside the sensor the ozone reacts first chemically with the electrolyte to form an electrochemically active compound which moves by diffusion to the working electrode. At the electrode the compound is oxidized. This causes a current corresponding to the partial pressure of the dissolved ozone.
The sensor has a very short response time of approx. 4,5 seconds for t 90% and streaming as it is well-known from all the other membrane covered electrochemical sensors is not necessary, so that profiling with very high local resolution is possible. Both turbid and coloured solutions do not interfere with the signal. For measuring the ozone concentration the sensor has to be combined with a temperature measurement.
The ozone micro-sensor is available for insitu measurements of pressures of up to 10 bar and for laboratory use. All sensors are delivered with sensor slope, temperature compensation data and mathematical formulas for calculating the ozone concentration. The exchange of sensor heads is very easy and could be done by the customer itself. The alternative exchange tip for dissolved oxygen extends the sensors flexibility.
