Radim 3AT

Continual Radon Monitor RADIM 3AT

In 2017 the TESLA company took over know-how from Jiri Plch – SMM and became manufacturer and seller of precize continuos monitor of radon concentration with marking RADIM 3AT. This czech legendary measuring instrument is the result of longtime expirience and development. It is measuring instrument with large volume measuring chamber and with very sensitive photodetector. Though use of PC and application is possible to show measured data in graph and export it for another data processing. Simultaneously TESLA became service department for existing series of RADIM measuring instruments. We also offer upgrade of older instruments to newest type. Our goal is inovation of product with modern access technology.
