PRE-ORDER ONLY. Due to a supplier issue with our circuit boards, we are able to accept orders but you will not get the device shipped immediately. Shipping time may be four weeks but we will update this message with more information as we get it.

The PurpleAir PA-II-FLEX is the latest sensor from PurpleAir. It is an air quality sensor that measures real-time PM2.5 concentrations for residential, commercial, or industrial use. Containing a full-color LED, the resulting glow indicates real-time air quality at a glance. Built-in WiFi enables the air quality detector to transmit data to the PurpleAir map, where it is stored and made available to any smart device.

For locations with limited or no WiFi access, the PA-II-FLEX PM2.5 measurement device incorporates real-time clock and SD card capabilities, allowing the sensor to record and store data on a microSD card.

The PA-II-FLEX features user-replaceable PMS6003 laser counters and there is an expansion port that allows easy swapping of the temperature sensors (yes, there are two) or expanding the capabilities of the sensor in the future.

The power option includes a specialized, high-quality outdoor (IP68 rated) USB power supply with 17 feet of cable to safely power your sensor outdoors.

FCC Compliance Statement (Part 15.19) This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. Warning (Part 15.21) Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. FCC Interference Statement (Part 15.105 (b)) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. To comply with FCC/IC RF exposure limits for general population / uncontrolled exposure, the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
