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.
