This Wireless Handheld Radiation Alert Detector allows 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 by wireless connection with Bluetooth right to your computer! It also has a red count light, a beeper sound and selectable alarm thresholds for quick assessments.

*REQUIRES A PC / SMART PHONE / PALM PILOT / LAPTOP THAT HAS WINDOWS XP / 98 / 2000 AND HAS BLUETOOTH CAPABILITES IN ORDER TO DISPLAY READINGS.
