Which Pocket Model is right for me?
 
bulletDX-1 - Detects Beta, Gamma, and X-rays on an analog meter to 10 mR/hr.  An affordable and simple to use Geiger counter for general purposes or for the hobbyist - adequate for a basic determination of whether or not something is radioactive.  Price: $289
bulletDX-2 - Identical to the DX-1, but with a higher ranging meter, up to 100 mR/hr. If you want to not only detect radioactivity, but also to quantify higher levels, for instance at 15 mR/hr versus 60 mR/hr, then the DX-2 would be preferable to the DX-1.  Price: $309
bulletMonitor 4 - An excellent all-around pocket Geiger counter that detects Alpha, Beta, Gamma, and X-rays up to 50 mR/hr, and offers switchable operating ranges, an especially nice feature for low levels of radioactivity - you can set it to the most sensitive operating range so the analog meter is easier to read, i.e. the needle will "jump" that much farther for the same level of radioactivity.  Price: $349
bulletMonitor 4 Kit - For those who want to save money off the factory built and calibrated Monitor 4, and who also enjoy building electronic kits from scratch.  Price: $239
bulletMonitor 4EC - A specialized version of the Monitor 4, with an energy compensated Geiger-Mueller tube that offers a more accurate linear reading for Gamma and X-rays (above 40 keV), making the EC model especially suitable for checking X-Ray machines for leaksPrice - $389
bulletMC1K - Another specialized version from the Monitor 4 line that offers Gamma and X-Ray detection at very high levels, up to 1,000 mR/hrPrice - $365
bulletRadalert 100 - An excellent all-around pocket Geiger counter that detects Alpha, Beta, Gamma, and X-rays up to 100 mR/hr, but does so with a digital readout instead of an analog meter.  It is comparable in sensitivity to the Monitor 4, but offers a user-adjustable audible alert.  It also has a mode for accumulating Total Counts, making it very easy to establish a background radiation level.  The Radalert incorporates a data port for output to a computer, along with optional software.  Price: $429
bulletCRM-100 - A more affordable version of the Radalert 100 for those who do not need the user adjustable audible alert feature.  Price: $359
bulletPRM-8000 - Newly released in July 2011, this American made instrument should generally be compared to the Radalert/Digilert 100 series, in that it uses the same standard GM tube capable of detecting Alpha, Beta, Gamma, and X-Rays, reading out also in a digital LCD display.  Its operating range is twice as high, however up to 200 mR/hr, and the PRM-8000 is alone among our selection of pocket models in offering a self-contained logging feature and long-life alkaline battery power (3 years).  Like The Radalert, the PRM also incorporates a Timed Count feature, an audible Alert, and data port for optional software.  Price: $469
bulletInspector - Among the most sensitive pocket Geiger counters available, a very popular unit, and perhaps the best hand-held unit ever.  Its oversized pancake styled Geiger-Mueller tube detects the lowest levels of Alpha, Beta, Gamma, and X-rays, making it suitable for higher sensitive applications such as checking food for radioactive contamination.  Plus, the Inspector offers a digital readout to 100 mR/hr, versus an analog meter, has an adjustable timer to set sampling periods, and a data port for output to a computer, along with optional software.  The newer version of the Inspector, called the Inspector Alert or Inspector +, offers the same user-adjustable audible alert as in the Radalert 100  Price: $549
bulletPRM-9000 - Almost identical to its PRM-8000 predecessor, but fitted with the same ultra-sensitive pancake-style GM tube as in the Inspector.  When deciding between the Inspector and the PRM-9000, choose the former for its simpler and more user-friendly interface, or opt for the PRM-9000 to obtain a more full-featured instrument with comprehensive statistical data, as well as a true data logging feature.  Like the 8000, the PRM-9000 also features an incredibly long battery life.  Price: $595
