TERRA with Bluetooth channel
Description
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. Measurement results can also be transferred to a personal computer.
TERRA has a large display with luminescent backlight, which simultaneously indicates units of measurement, measurement error, threshold level and real time, as well as ten-segment analog indicator of registered radiation intensity. The dosimeter has a built-in memory for 1200 measurements. Sound, vibration and sound-vibration alarms are provided for convenience of use.
New software “RadReader” has been developed for operation with the MKS-05 “TERRA” dosimeter-radiometer.
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. TERRA is also supplied to the Army and the Ministry of Emergency Situations of Kazakhstan.
Since 2002 according to the international technical assistance programs TERRA devices have been supplied to the Border Guard Service of Ukraine, Internal Troops of the Ministry of Internal Affairs of Ukraine, the State Emergency Service of Ukraine, the Border Services of Kazakhstan and Uzbekistan.
