PurpleAir Air Quality Sensor PA-II-SD (22509) Check Availability

The PurpleAir PA-II-SD is an air quality sensor that measures real-time concentrations of airborne particulate matter including PM1.0, PM2.5, and PM10. The sensor also measures air pressure, temperature, and humidity, though air temperatures are considered “for interest only” as the measured temperatures tend to run higher than ambient temperatures because of effects from the sensor casing and other factors.

The sensor has built in WiFi that enables air quality data to be viewed on PurpleAir’s real-time air quality map. Alternatively, the sensor can be deployed to record air quality data on the provided SD card.
