DOSIMETER TERRA MKS-05 (GEIGER COUNTER) ENGLISH VERSION

MKS-05 "TERRA"- multifunctional radiometer-dosimeter. MKS-05 "TERRA" is fully functional radiation-metric device. It use in army, in special government organizations.

It is professional device because its technical parameters correspond to the standards, shown to professional devices in many countries (see below).

For example, main differences from "household' dosimeters:

          - Five independent measuring channels with alternate indication of data on the single liquid crystal    display,

        - Prompt evaluation of gamma background within 10 seconds,

        - Measurement results averaging, manually and automatically interrupted,

        - Automatic subtraction of gamma background at measurement of beta contamination,

        - Digital display backlight,

        - Measurement time intervals for ED,

        - More wide measurements ranges (see table of parameters),

        - Increased shock resistance according military standard. 12 months guarantee
