Abacus Wireless Handheld Radiation Alert
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
Detector: Internal tube 1- Halogen-quenched, uncompensated GM pancake tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.75 in.). Internal tube 2- Halogen-quenched, uncompensated thin wall beta-gamma GM peanut tube Radiation symbol on front and top labels mark the center of the detectors. Display: Windows Mobile™ PocketPCs, Palm™ Pilots or Windows™ based laptop or desktop computer.
Exposure Rate: µR/h - 0 to 2,000,000 µR/h; mR/h - 0 to 2,000 mR/h; µSv/h - 0 to 20,000 µSv/h. Count Rate: cpm - 0 to 750,000 cpm, cps - 0 to 12,500 cps. Sample Counting: Total counts - >99,999,999,999. Accuracy: Typically ±15% of reading. Alert Set Range: mR/hr .001 - 50 and CPM 1 - 160,000. Gamma Sensitivity: 7.5 CPS/mR/hr referenced to Co60.
