Manufacturer/Model:
Aeroqual S-500 OZU Pollutant: Ozone Measurement Range:
0-0.15 ppm Type: Metal Oxide Time Resolution: 1 Minute
Overall, the three Aeroqual sensors showed high accuracy, compared to the FRM ozone monitor, for a concentration range between 0 to 150 ppb.
The three Aeroqual sensors exhibited high precision during most of the tested environmental conditions. Except for high temperature and
humidity, sensors had some difficulties recording low concentration ozone.
The three Aeroqual sensors showed low intra-model variability, as well as good data recovery (100%).
They have high correlation with the FRM instrument from both the field (R2 > 0.85) and laboratory studies (R2 > 0.99).
Deployment period 02/10/2015- 04/04/2015: the three Aeroqual sensors followed the ozone concentration change as monitored by FRM instrument.
The units showed 100% data recovery.
The units have low intra-model variability (+/- 10%).
Coefficient of Determination (R2) quantifies how the three sensors followed the ozone concentration change by FRM.
An R2 approaching the value of 1 reflects a near perfect agreement, whereas a value of 0 indicates a complete lack of
correlation.

Low Pollutant Level
Sensor’s ability of generating precise measurements of ozone concentration at low, medium, and high pollutant levels were evaluated under 9 combinations of T and RH, including extreme weather conditions like cold and humid (5 °C and 65%), hot and humid (35 °C and 65%), or hot and dry (35 °C and 15%).

Accuracy was evaluated by a concentration ramping experiment at 20 °C and 40%. The sensor’s readings at each ramping steady state are compared to the reference instrument.
The higher the positive value (close to 100%), the higher the sensor’s accuracy.
