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 workplace, in the workshop or in the lab. Operation via the wireless touch panel is intuitive and easy.

  • Lithium battery for 8 h operation
  • Simultaneous measurement of PM1, PM2.5, PM4, PM10, Cn and particle size distributions
  • Measures reliably from lowest to highest concentrations
  • Simple calibration by the customer on-site
  • Measurement ranges:
    • 150 nm - 18 μm
    • 150 nm - 93 μm

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 a few seconds.

Simple to evaluate

For transparency in fine dust matters

The Fidas® Frog user interface can be used to display all measurement series and compare them with each other. Fast printouts of reports are easily possible. With the integrated camera, images of the measurement set- up can be conveniently assigned to the data record and the measurement report. A warning message is displayed if individual limits or legal thresholds are exceeded.

The best compressed

We are also breaking new ground in terms of our manufacturing processes. The polymer 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 system. Fidas® Frog uses an optoelectronic detector, which measures accurately and with high resolution.

As well as wireless communication, IoT also comes as standard with Fidas® Frog.
