  • Product Description

    PRM-8000 Digital Pocket Geiger Counter

      After more than two years in development - the PRM-8000, a new model of Digital    Pocket Geiger Counter designed to detect Alpha, Beta, Gamma, and   X-Radiation, displaying through a digital readout, and emitting an audible   click with each radiation count detected.

      This is a very high quality, professionally engineered and built   pocket-sized radiation detector Made in the USA.  The PRM-8000 is   not just another dosimeter rushed to the market to take advantage of the   current crisis - it is thoroughly tested, and as a Geiger Counter,   instead of a dosimeter, it is designed to provide   immediate warning of radiation danger.

      The PRM-8000 is designed to be "Always On" at the user's option, and in   that state, continuously monitors Current,   Average, Maximum and Minimum Radiation Levels.  This powered mode is made   possible by an ultra-efficient hardware and software design that gives an   incredible 3 year battery life, yet from a standard 9V alkaline   battery.

    Given the need to check radiation levels from the Fukushima plant, the   PRM-8000 display can be converted fromEnglish to Japanese language characters   (see example at left).

      The PRM-8000 includes an automatic Timed Measurement or Timed Count   feature that is necessary to reveal low level contamination, that might   otherwise be missed from a momentary scan.

      And the photo at right shows the thin mica end window of the PRM-8000   available at the top of the instrument, enabling the detection of alpha   radiation which, if ingested, can be potentially dangerous.

    Other Features:



    Two-line, alpha-numeric display with backlight to support low-light conditions. 


    Display Units - uR/hr, mR/hr, uSv/hr,   CPS and CPM


    0.001 - 200mR/hr Range


    The device's unique Radiation Monitoring Engine (RME) is   always-on collecting measurements enabling rapid environment assessment.


    Using only one key, users can scroll through several   screens that display present, average, maximum and minimum measurements in   uR/hr, mR/hr, uSv/hr, Counts per Second (CPS) or Counts per Minute (CPM).


    The PRM-8000 instrument not only records the maximum   radiation measured, but also displays the time and date at which the maximum   occurred.


    Visual and audible Indicators, including flashing LED   with each radiation count


    A user-settable dose rate alarm sounds an audible alert   when the measured radiation level exceeds that of the alarm level setting.


    With over 100K bytes of data logging memory included, the   PRM-8000 can autonomously store up to 91,466 minutes or hours of time-stamped   measurements. These measurements can then be uploaded to a PC in industry   standard CSV format   for analysis.  Optional USB cable available.


    Designed by Mazur Instruments and manufactured in the   USA, the PRM-8000 includes abundant I/O options including support for   headphones, external speakers, external power and USB data exchange.


    Instruction manual in booklet form   included.

    The price   below includes the Carrying Case shown at right (cable   optional).



      This item typically ships within 1 business day.
