TERRA-P+

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!

Sales price: 199,00 €

Description

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)

Purpose of Use
