Dosimeter-Radiometer MKS-05 «Terra-P+»
Terra-P+ is a new version of world-known dosimeter TERRA-P, launched by Ecotest TM in 2011. The device gained a range of new features. It has 5 independent measuring channels with alternate indication of data on the single liquid crystal display with digital backlight. From now a household dosimeter Terra-P+ can measure surface beta-particles flux density with capability of automatic subtraction of gamma background!
In comparison with "TERRA-P" dosimeter-radiometer, "TERRA-P +" has new features:
- gamma radiation ambient dose equivalent rate
- gamma radiation ambient dose equivalent
- surface beta-particles flux density
- apartments and offices,
- items of everyday use,
- clothes,
- means of transportation,
- bank-notes,
- building materials,
- ground surface of infields,
- food items (especially berries and mushrooms)
