Product Description  
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!
New capabilities of Terra-P+
In comparison with “TERRA-P” dosimeter-radiometer, “TERRA-P +” has new features:

wider measurement range of gamma radiation ambient dose equivalent rate
measurement of surface beta-particles flux density
measurement of ambient dose equivalent accumulation time
automatic subtraction of gamma background at measurement of beta contamination
programming of threshold level values:

          – gamma radiation ambient dose equivalent rate
          – gamma radiation ambient dose equivalent
          – surface beta-particles flux density

digital display backlight
wider operating temperature range

TERRA-P+ is used to:

control personal radiation safety of the user
carry out radiation monitoring of:

          – 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)
