Electrochemical ozone sensors: A miniaturised alternative ...

Mar 01, 2017· 1. Introduction. Ozone sensors are a technology for O 3 detection that are characterised as being compact in size, low cost, low power and fast response. Most commercially available O 3 sensors use either electrochemical sensing principles or are based on semiconductor O 3 sensors. Such O 3 sensors have in principle sufficient sensitivity to be used in the ppb-range as air quality monitors …

Manual

When the ozone gas exists, the sensor’s conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ131 ozone gas sensor has high sensitivity to ozone, and also has sensitivity to strong oxide such as Cl 2, NO 2 &etc.

How Scientists Measure the Ozone - HowStuffWorks

Apr 29, 2008· Scientists are able to study the amount of ozone in a given vertical column of atmosphere by using various instruments. One such instrument is an ozonesonde ("sonde" comes from Old English, meaning messenger), which includes a balloon that carries the instrument up more than 21 miles ( kilometers) high to the stratosphere [source: NOAA].In the stratosphere, it sucks in and holds air to ...
