Description

AQ Guard Smart 2000 is a measuring device for monitoring particle concentrations in the ultrafine range. These ultrafine particles (UFP) significantly impact health, according to the World Health Organization (WHO). The who has therefore been recommending their monitoring since 2021. They typically cannot be detected by optical aerosol photometers or spectrometers due to their small size

Mass limit values such as PM2.5 and PM10 can be measured well with gravimetric methods; at the latest, for smaller PM1, ultrafine fractions are difficult to estimate and can be meaningfully assessed only by determining the particle concentration.

Expensive and more maintenance-intensive condensation particle counters are usually used to measure ultrafine particles. A size-classifying system (Scanning Mobility Particle Sizer) can make statements about particle size distribution and concentration.

Air quality analyzer for monitoring nanoparticles

AQ Guard Smart 2000 for ultrafine particles closes the gap between classical condensation particle counters and optical systems. Long-term measurements for the evaluation of number concentrations indoors and outdoors, e.g., at highly polluted locations such as airports, main roads, forwarding agencies, or also, e.g., toll stations, are quickly and reliably possible. They can already be used to define avoidance and reduction measures in a meaningful and targeted way.


Extensions / Accessories

To better understand the fine dust input and its cause, the device is optionally available with a corresponding weather station, which provides supplementary meteorological information. Sensors that measure temperature, humidity, and pressure are integrated as standard. AQ Guard Smart System has a pole or tripod mount and can be extended with a sunshade and a LoRa modem if required.

The cloud application MyAtmosphere enables private and government operators to retrieve current measured values directly, compare them with other devices without time delay and further processing, or integrate them into their systems/environments via an optional programming interface (API).

Benefits

  • Simple and accurate monitoring of particle number concentration of UFP
