After more than 2.5 years of research and development, we can finally present our vision in every city or urban area. Of course, this is not possible without proper certification and calibration. 

We are pleased to announce that our improved sensor design has been tested and calibrated by one of the highest caliber professionals:

Version 2.0 of Multi-Micro Sensor Device (MMSD) by Sparrow is tested and calibrated in the climate chamber newly developed by METAS. Swiss Federal Institute of Metrology. Calibration is vital for air pollution sensors to deliver reliable data from measurements. We thank METAS for its excellent support and professional assistance. 

Without this, it is impossible to get a correct picture of air quality and in today’s cities.
