AQLite Air Monitoring Packages
The AQLite's actively ventilated, mountable NEMA enclosure and low power requirement (15 watt or less, depending on package choices) are ideal for operating the unit with the user's solar panel, opening the door for vast networks of AQLites to be deployed in remote outdoor locations as well as roadside and urban settings.
The AQLite-Standard package combines our US EPA approved Federal Equivalent Method (FEM) Model 108-L Ozone Monitor with robust and reliable sensors that measure CO2, particulate matter (PM1, PM2.5), pressure (P), instrument temperature (T), and instrument relative humidity (RH). In the AQLite-Customizable packages, any two of the following sensors can be added to the AQLite-Standard's measurement suite: CO, NO2, SO2, total VOCs. The AQLite-Standard and Customizable packages can be purchased with the option to upload data directly to the Cloud via cellular for easy access using the 2B Tech Data Portal. An optional vehicle mounting system can be used for mobile monitoring. The optional weather station enables expanded meteorological data.
In addition to the AQLite-Standard, other configurations are available as described below.
