1 Dust Sentry / Dust Sentry Pro / AQS 1 Introduction
1.1 Overview
Dust Sentry / Dust Sentry Pro / AQS 1 (collectively referred to herein as
‘monitors’) are tools for air
quality professionals to target specific applications of interest in industrial, urban environment and
regulatory applications. It is a flexible air quality monitoring system that can be configured for a range
of uses.
Key technology features of the monitors enable them to deliver data with very strong correlation to
EPA-approved monitors
– ‘Near Reference’ – over extended periods of time; several years with
appropriate maintenance.
Housed in a rugged, lockable weatherproof (IP 65) enclosure, the monitors include an embedded PC
and full software system for remote technical support, data management and analytics.
Users can make use of the embedded PC running proprietary
Aeroqual Connect
software, or
optional web-based
Aeroqual Cloud
software for data storage and management of networks of
monitors.
