Abacus Wireless Handheld Radiation Alert® Detector
Windows Desktops and Laptops, Windows Mobile Devices & PalmOS
The Abacus is a handheld, digital radiation detection device that enables you to complete your surveys automatically with your Abacus and a Windows Mobile™, Palm™ Pilot or Windows™ Computer. Not only does it offer excellent sensitivity to low levels of alpha, gamma, and x-rays, but the internal "guard" detector automatically performs gamma subtraction from the "pancake" detector for unprecedented beta sensitivity. The software can display a variety of units for a wide array of applications, take timed counts, control the audio of each tube, and save your surveys for easy analysis and sharing, all wirelessly with Bluetooth® right to your computer! The Abacus also has a red count light, a beeper sound and selectable alarm thresholds for quick assessments.

The stainless steel WipeTest Plate slides easily onto the Abacus positioning the depression and wipe directly in front of the GM tube window at a fixed distance of 1 centimeter. The WipeTest plate is removable for general surveying or decontamination. It can also be used for protecting the GM from damage and the instrument from being contaminated while the Abacus is not in use. (patent #5,936,246) |
