AQ Guard

Description of item
Compact ambient air quality monitor. Featuring highly precise fine dust measurement, CO2 and TVOC, Palas® Air Quality and Infection Risk Index.

SKU: AQ Guard Categories: ,

Features And Benefits
• Technology based on the type approved Fidas ® 200 series (EN16450 and MCERTS); simultaneous measurement of Cn, PM1, PM2.5, PM4, PM10.
• Computation of air quality index based on measurements of particulates, CO2 and VOC.
• High accuracy due to advanced algorithms.
• Long term stable due to self calibration for measurement of flow rate, particulates, and gaseous pollutants.
• 2 years operation without calibration.
• Operates on AC, DC, or power-over-Ethernet.

• Industry:
                  – Production processes
                  – Bulk material handling (mixing, discharge, storage, packaging etc)
                  – Fenceline Monitoring
• Construction sites: Roads, railroads, demolition sites.
• Buildings: Schools, kindergartens, hospitals, hotels, offices, public service buildings.
• Residential buildings near construction sites or other polluted areas.
• Public transportation: Airports, train stations, tramway underground stations, cruise ships, passenger cabin, e.g. in tram, train.
