The Abacus is a handheld, digital radiation detection device that enables you to complete your surveys automatically with your Abacus and a Pocket PC, 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.
