Personal Radiation Detection Devices Products CRM-100

Description:

The CRM-100™ is a general purpose Geiger counter that measures alpha, beta, gamma, and x-radiation intended for personal safety and educational purposes. The CRM-100™ features a 3-second update on its digital liquid crystal display (LCD). The LCD shows current radiation levels in milliroentgens per hour from .001 to 110 or counts per minute (cpm) from 0 to 350,000. Select SI units and the LCD shows readings in microsieverts per hour from .01 to 1100 or counts per second (cps) from 0 to 3,500.

This personal radiation detection device also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours. Additionally, a red LED will blink and a beeper will chirp with each count. This device is very easy to use and recommended for anyone that wants affordable peace of mind. The CRM-100™ is ideal for accurately measuring low levels of radiation.
