The Radalert™ 100 is a general purpose Geiger counter and like the CRM 100 measures alpha, beta, gamma, and x-radiation. Exciting new features of the Radalert 100 include a three-second update and a utility menu that allows you to change the default settings for several operating parameters. The digital liquid crystal display (LCD) shows the current radiation level in your choice of milliroentgens per hour from .001 to 110 or counts per minute (cpm) from 0 to 350,000. When SI units are selected, the LCD shows readings in microsieverts per hour from .01 to 1100 or counts per second (cps) from 0 to 3,500. This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours. A red LED blinks and a beeper chirps with each count. An audible alert sounds when the radiation reaches a user-adjustable level. The Radalert® 100 meets CE certification requirements for Europe.
