ES-O₃-L

• Rapid measurements of dissolved ozone.
• Calibrated and ready to use.
• Ideal for solutions with depths less than 1m.
• Data loggers are available if required.

This laboratory amperometric AMT ozone microsensor has been developed above for fast in-situ and online ozone measurement and for watching ozone concentrations in industrial applications.

For measuring the ozone concentration, the sensor must be combined with a temperature measurement. Edaphic Scientific can supply a temperature sensor upon request.

The working principle of the sensor could be explained simply as follows: Because of the partial pressure of the gaseous ozone, the analyte is separated by permeation through the membrane. Inside the sensor, the ozone reacts electrochemically at the working electrode. This causes a current corresponding to the partial pressure of the dissolved ozone.

As it is well-known from all the other membrane-covered electrochemical sensors, streaming of the membrane is not necessary. Due to the micro-sensor technology, measurements with high local resolutions of some micrometers are possible.

Both turbid and coloured solutions do not interfere with the signal.

The sensor includes an integrated electronic device for the transformation of the sensor current into a voltage of 0...+ 3 V (DC). The main working range is mostly between 0 and 1 V DC output.

All sensors are delivered with sensor slope, temperature compensation data and mathematical formulas for calculating the ozone concentration. The exchange of sensor tips is very easy.

Please note that the sensor delivers only the raw data (mV) and that you must use a temperature sensor for temperature measurements to compensate for the O₃ sensor’s temperature dependence.
