Fidas® Frog

Battery powered, portable fine dust measurement device with detachable control panel, for outdoor, indoor and workplace measurements based on EN 481

The fine dust measurement device Fidas® Frog allows for a fast, reliable, and quality-assured determination of fine dust, e.g., monitoring within the scope of Health, Safety, and Environment (HSE) management at workplaces (exposure assessment) or in the range of indoor air quality measurements (e.g., for offices, public buildings such as schools, passenger compartments...).

It simultaneously measures the environmentally relevant mass fractions PM1, PM2.5, PM4, PM10, and TSP, as well as the particle number and the particle size distribution within the particle size range of 0.18 – 93 µm. By providing fine dust values with high time resolution, the operator receives comprehensive information for evaluation and assessment of the fine dust pollution for the investigated application.

The very compact and light design as a portable hand-held monitor with either battery or mains power operation and the operation time of up to 8 hours per battery charge allow for a flexible application of the Fidas® Frog at any measurement sites.
