AQ Guard : Measuring device for monitoring indoor air quality
Product Descriptions
AQ Guard : Measuring device for monitoring indoor air quality. Measurement of dust concentrations starting at 150nm(*1)incl. CO2 and tVOC for calculation of air quality and infection risk index.
• Technology based on the type approved Fidas® 200 series (EN16450 and MCERTS); simultaneous measurement of Cn, PM1, PM2.5, PM4, PM10
• With “Indoor Air Hygiene Professional” extension- increased counting efficiency for nano-scaled particles from 150nm
• Computation of air quality index based on measurements of particulates, CO2, and VOC
• Estimation of infection risk based on measurements of CO2 and particulate matter
• 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-Etherne
