    Description

    TERRA is a professional device for official measurements, which measures the level of gamma background, beta contamination, accumulated dose, and its accumulation time.
    TERRA is exported to over 70 countries. The device is in operation in many Governmental Institutions and Agencies worldwide.

    TERRA designed exactly for your needs if you:

    • want to be sure of your radiation safety
    • take care of your family
    • are aware of possible radiation risks
    • have a healthy diet
    • own real estate or have projects under construction
    • prefer active leisure time (tourism, hunting, fishing, skiing, etc.)
    • like travelling
    • use cash
    • want to choose a useful and original gift for the loved ones
    • live your best life
    • want to be a professional in all areas

    Purpose of Use

    • Measurement of ambient dose equivalent rate (DER) of gamma and X-ray radiation (photon-ionizing radiation)

    • Measurement of ambient dose equivalent (DE) of gamma and X- ray radiation

    • Measurement of surface beta-particles flux density

    • Measurement of ambient dose equivalent accumulation time

    Features

    • Big display with luminescent backlight

    • Simultaneous indication of units of measurement, measurement errors, threshold level, and real-time on the display

    • Analog ten-segment indicator of registered radiation intensity

    • Ability to perform measurements with a preset error

    • Four-level indication of battery discharge

    • Built-in memory which allows storing up to 1200 measurements

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

    • Built-in gamma, beta-sensitive Geiger-Muller counter

    • Prompt evaluation of gamma background within 10 seconds

    • Automatic subtraction of gamma background at measurement of beta contamination

    • Measurement results averaging, manually and automatically interrupted

    • Automatic setting of measurement intervals and ranges

    • Audio, vibration, and vibration-audio alarm of each detected gamma-quantum or beta-particle that can be switched off

    • Two-tone audio, vibration, and vibration-audio alarm of exceeded programmed threshold levels

    • Clock and alarm clock
