AeroNanoTech has been established by leading scientists representing famous Russian school of aerosol science and technology leaded by Profs Fuchs and Petryanov. The main aim of the company is to develop state of the art technologies and apparatus for monitoring and control of wide range of airborne particles in indoor and outdoor environments. The first technology offered by the company is Diffusion Aerosol Spectrometer capable of monitoring airborne particles within the range of 3 to 200 nm. At this stage, we are commencing production of a number of devices, including automated filter testing setup, real time diffusion battery, water testing apparatus, submicron particle counter and thermophoretic particle precipitator, which will be made available within next few month.
