Quantity: One Radalert 100 Digital Geiger Counter - Radiation Detector. Far more accurate than those old civil defense geigers, the Radalert 100 is a modern, digitally accurate, general purpose geiger counter. The Radalert 100 measures alpha, beta, gamma, and even x-radiation. The digital display shows readings in your choice of counts per minute (cpm) or mR/hr, up to 100,000 cpm or 100 mR/hr, or in accumulated counts. A red LED blinks and a beeper chirps with each count (the chirp can be muted). An audible alert sounds when the radiation reaches a user-adjustable level. The standard Data out port can send counts to computers, data loggers, educational data collection systems and other CMOS-compatible devices. A submini jack provides audio output to an external earpiece, amplifier, or tape recorder.
