Analog Radiation Detector Comparison Posted on April 28, 2018May 7, 2018 A number of radiation industry professionals still prefer analog radiation detectors even today. Here at SEI, we ditched the lunch box design common in a number of analog meters for something a little more smaller. The following radiation detector comparison will help you nail down the right analog Geiger counter for your needs. Our Monitor 4 is a “hot dog tube” based Geiger Counter. Of the three versions listed, this model had been in production the longest. What started as a small brown square case that established it as an industry standard, has now become a much more ergonomic design with all the same features customers have come to love. Some customers need the Monitor 4EC, which is the energy compensated alternative with the same operating range. If you’re in need of a higher operating range, such as 1000 mR/hr, then the energy compensated MC1K is reporting for duty. Both EC (energy compensated) are ideal for applications requiring a linear response to gamma and X-rays. The rest of the spec comparison are rounded out in the table below.
