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!

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,
