Dosimeter-Radiometer with Bluetooth channel

МКS-05 TERRA

TERRA is a professional device for official measurements, which measures the level of gamma background, beta contamination, accumulated dose and its accumulation time.

Measurement results of the device can be transferred to smartphones and tablets running Android™ OS via Bluetooth channel in real-time. A specially designed “GS Ecotest” application is available on Google Play.

TERRA is exported to over 70 countries. The device is in operation in many Governmental Institutions and Agencies worldwide.
