Description
Ecotest TERRA-P Plus is a new version of the world-known household dosimeter TERRA-P, designed on the basis of professional device MKS-05 TERRA.
TERRA-P Plus dosimeter has the following new features:
– wider measurement range of gamma background;
– measurement of beta-contamination;
– measurement of dose accumulation time;
– automatic subtraction of gamma background at measurement of beta contamination;
Purpose of use
Measurement of gamma radiation ambient dose equivalent rate;
Measurement of gamma radiation ambient dose equivalent;
Measurement of surface beta-particles flux density;
Measurement of ambient dose equivalent accumulation time;
Real time measurement (clock).
Features
Five independent measuring channels with alternate indication of data on the single liquid crystal display;
Built-in gamma, beta sensitive Geiger-Muller counter;
Automatic setting of measurement intervals and ranges;
Audio signaling of each detected gamma-quantum and beta-particle;
Two-tone audio alarm of exceeded programmed threshold levels;
Digital display backlight;
Two AAA size batteries;
Low battery indication;
Shock resistant body;
Small weight and dimension parameters.
