AQLite - Air Monitoring Packages System
The AQLite Monitoring Packages are the ultimate combination of performance and size for an air quality measurement system. These packages combine our US EPA approved Federal Equivalent Method (FEM) Model 108-L Ozone Monitor with proven sensor technology for other pollutants in a customizable package that can be deployed in a wide variety of air monitoring applications.
The actively ventilated, mountable NEMA enclosure and low power requirement (15 watt) of the AQLite are ideal for operating the unit with a solar panel; opening the door for vast networks of AQLites to be deployed in outdoor locations.
The AQLite-Standard package combines the FEM ozone monitor with robust and reliable sensors that measure CO, CO2, particulate matter (PM1, PM2.5)*, temperature (T), pressure (P) and relative humidity (RH). The AQLite has the ability to upload data directly to the Cloud using a 2G/3G/LTE cellular upload for easy access.
In addition to the AQLite-Standard, other configurations are available as described below.
- Configurations available for measuring O3, CO, CO2, PM1, PM2.5, SO2, NO2
- Measurements of ambient temperature (T), pressure (P), and relative humidity (RH) present in the data stream for the AQLite-Standard and AQLite-Customizable configurations
- Panels available for mounting upon request
- O3 measurements using a highly accurate FEM ozone monitor with a small footprint
- AQTreks mobile application (iOS and Android) for real-time mapping and graphing of data
- 2G/3G/LTE real time cellular data transmission to the cloud
- MicroSD data storage
- RS232 and RS485 (with Modbus over RS485) data outputs coming soon
- Solar Power option available for remote applications coming soon
- AQLite Basic Package: Ozone (O3) only
- AQLite Standard Package: O3, carbon monoxide (CO), carbon dioxide (CO2), and particulate matter (PM1, PM2.5)
- AQLite Customizable Packages: O3, PM1/PM2.5, and CO2 and up to two of following sensors: CO, sulfur dioxide (SO2), or nitrogen dioxide (NO2)
