AQ Guard is Measuring device for monitoring indoor air quality Measurement of dust concentrations starting at 150 nm (*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 150 nm
  • 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-Ethernet

Dilution system – LDD 100

The dilution of large droplets is particularly important when measuring highly concentrated droplet aerosols. Since large droplets are difficult to dilute, standard systems only work up to a size of 1 – 2 μm. The newly developed dilution system LDD 10 (dilution factor 10) is the first system to dilute almost loss-free large droplets up to 10 μm.
