Product Description

The W100140/SEF2/W838b is a general purpose geiger counter that measures alpha, beta, gamma, and x-radiation. Exciting new features of the W100140/SEF2/W838b — as an upgraded version of the popular Radalert 50 — include a three-second update and a utility menu that allows you to change the default settings for several operating parameters. Its 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 (the chirp can be muted). An audible alert sounds when the radiation reaches a user-adjustable level. The W100140/SEF2/W838b meets CE certification requirements for Europe.
Use the W100140/SEF2/W838b to:

Monitor personal radiation exposure
Monitor an area or perimeter
Detect radiation leaks and contamination
Ensure regulatory compliance
Monitor changes in background radiation
Demonstrate principles of nuclear physics
Check for radioactive minerals in the earth
