Fidas Frog

Breaking new ground with Fidas® Frog. This fine dust aerosol spectrometer is small, light and precise. The battery life is sufficient for a whole working day – for example for measuring the fine dust load at an office workstation, in the workshop or in the lab. Operation via the wireless touch panel is intuitive and easy.

  • Battery life of 8 hours
  • Simultaneous measurement of PM1, PM2.5, PM4, PM10 and particle size distributions
  • Also measures reliably at higher concentrations
  • Simple calibration by the customer on-site

Light. Small.
Standalone device.


Fidas® Frog is smaller than a shoe box and uses WLAN to communicate with its operator via the operating panel. The wireless operating panel allows users to perform measurements at a great distance from the particle source. Thanks to the impressive battery life of 8 hours, you can take measurements throughout an entire working day – with a time resolution of individual seconds.

Fidas® Frog is based on the sensor and measurement algorithm from the tried and tested Fidas® 200, which is certified by TÜV Rheinland. This is how we ensure exact measurements for the PM1, PM2.5, PM4 and PM10 particle measurement ranges. All of the standard particle size distributions are displayed.

The best compressed

We are also breaking new ground in terms of our manufacturing processes. The housing and various components are generated with 3D printing techniques. The sensor has been further refined and is based on the sensor of the certified Fidas® 200 S system. It is made from lightweight plastic. Fidas® Frog uses an optoelectronic detector, which measures even more accurately and with even higher resolution. At the same time, it is smaller than its predecessor. As well as wireless communication, IoT also comes as standard with Fidas® Frog.
