Product Description  
A compact search device with telescopic tube for quick detection and localization of gamma and beta radiation sources.
5 seconds are enough for quick evaluation of gamma background with 4 built-in Geiger-Muller counters. A big display with luminescent backlight simultaneously indicates units of measurement, measurement errors, threshold level and real time. Analog indicator of radiation intensity facilitates localization of radiation sources. The device has a built-in memory for 1200 measurements and 999 objects of inspection.

STORA-TU can also transfer measurement results to smartphones and tablets running Android OS in real time. With the help of GS Ecotest application this information is processed, displayed in a user-friendly way and stored in a special database. The GS Ecotest application can be downloaded from Google Play for free.
Measurement results can also be transferred to a personal computer through the Bluetooth channel.
