CitiSense
CARTOLA
Description
| The device uses a sensitive metal oxide semiconductor that relies on the conductance of heated tungstic oxide (WO3). In the presence of ozone, surface conductance of WO3 decreases. Changes in the conductance are calibrated to measure ozone concentrations. During a “flow” state the sensor responds to incoming ozone the sensor conductance decreases. The ozone measurement is proportional to the sensor conductance difference between a no-flow and flow states. |
