ECOTEST Radiation Geiger Counter MKS 05 Terra Pro

Terra MKS 05 Geiger Counter is a Professional Version of the popular Ecotest Dosimeters.  It detects the emission of nuclear radiation - beta particles and gamma raysPlease review the specifications below.

Purpose of use

  •     Measurement of gamma and X-ray radiation ambient dose equivalent rate.
  •     Measurement of gamma and X-ray radiation ambient dose equivalent.
  •     Measurement of surface beta-particles flux density.
  •     Measurement of dose equivalent accumulation time.
  •     Real time measurement (clock).


  •     Five independent measuring channels with alternate indication of data on the single liquid crystal display.
  •     Built-in gamma, beta sensitive Geiger-Muller counter.
  •     Prompt evaluation of gamma background within 10 seconds.
  •     Automatic subtraction of gamma background at measurement of beta contamination.
  •     Measurement results averaging, manually and automatically interrupted.
  •     Automatic setting of measurement intervals and ranges.
  •     Audio signalling of each detected gamma-quantum and beta-particle with possible switching off.
  •     Two-tone audio alarm of exceeded programmed threshold levels.
  •     Digital display backlight.
  •     Two AAA size batteries.
  •     Low battery indication.
  •     Shock resistant frame.
  •     Small weight and dimension parameters.
