Aeroqual - S500 (OZU 0-0.15)

General Description

The Aeroqual Series 500 handheld monitor can be used with a wide range of gas sensor heads. The sensor head used in this AQ-SPEC evaluation is the ozone OZU 0-0.15 ppm sensor head.

Principle of Operation

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.
