PRM-8000 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 recent crisis - it is thoroughly tested, and as a Geiger Counter, instead of a dosimeter, it is designed to provide immediate warning of radiation danger.
T
he 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.
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.
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.
Given the need to check radiation levels from the Fukushima plant, the PRM-8000 display can be converted from English to Japanese language characters (see example at left).
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 includes the Carrying Case shown at right (cable optional).
This item typically ships within 1 business day.
