This is a professional instrument for official measurements that measures the level of gamma background, beta contamination, accumulated dose and its accumulation time. Fast evaluation of gamma background takes place within 10 seconds. With the help of the GS Ecotest application, measurement results are transmitted in real-time to smartphones and tablets with Android ™ OS via a Bluetooth channel.
The GS Ecotest application is available on Google Play. Measurement results can also be transferred to a PC.
TERRAhas a large display with luminescent backlight, which simultaneously indicates units of measurement, measurement error, threshold level and real-time, as well as a ten-segment analogue indicator of registered radiation intensity. The dosimeter has a built-in memory for 1200 measurements. Sound, vibration and sound-vibration alarms are provided for the convenience of use.
The device is in operational service with the Ukrainian Army; it is included in the equipment list of the State Emergency Service of Ukraine, and used for the purposes of the Security Service of Ukraine, Ministry of Internal Affairs of Ukraine, and the State Border Guard Service of Ukraine.
