Geiger Muller Counter


Geiger Muller Counter, F2-2000.10, £177.00



The design of our GM Counter has been tailored to the requirement of schools. There are three main modes of operation:

  • Ratemeter - used to examine the properties of alpha, beta and gamma radiation.
  • Counter - gives the counts/minute at selectable intervals of 1 minute to 1 hour. Ideal for investigating half life. Up to 800 readings can be saved and remain after switch off.
  • Period Count - gives counts in a user selected time which can be from 5 seconds to 1 hour. This enables items which are only slightly radioactive to be studied e.g. walnuts.



The GM Counter is supplied with a 9V plugtop power supply. The GM tube connects to the jack socket at the side and it has its own internal high voltage supply. The Counter also can operate using our Battery Box. This makes the whole unit portable - opening the doors to new experiments.

The simplicity of setup and operation makes this an attractive proposition for any classroom.

Note the GM Tube is not supplied with the GM Counter.

A manual is available in the Teachers Section.

  This is a close up of the Counter screen showing the count interval, the last count(18), the current count(11), the number of readings taken(8) and the time to the start of the next reading(36s).
  This is the screen for selecting the period which can vary from five seconds to one hour.


The Counter and Period readings are always automatically saved in the Geiger Muller Counter and remain after switch off.
If you wish to operate on your data set then provision is made to transfer the data to the Excel on a PC. The software for this is available on the website.
  The statistics available are basic. For those wishing to plot and analyse graphs then export the data to Excel on a PC.
