A top famous product of “ECOTEST” trademark, which is exported to over 70 countries. This is a professional device for official measurements, which measures the level of gamma background, beta contamination, accumulated dose and its accumulation time. Prompt evaluation of gamma background is performed within 10 seconds. With the help of GS Ecotest application measurement results are transferred to smartphones and tablets running Android™ OS via Bluetooth channel in real time. The GS Ecotest application is available on Google Play.
