Radiation Detector | Radiation Meter

The Radiation Detector is standard industrial model of a Geiger-Muller tube with a thin mica output window. It is factory-calibrated using a pulse generator and is the standard +/- 15% of the full scale relative to Celsium- 137.

It offers a reliable result in milliroentgents/hour and events/minute (cpm) in three different  periods. The unit is protected by an anti saturation circuit up to a value equivalent to 100 times the maximum reading in the greatest interval. The radiation detected is indicated by the graduated scale, a blinking  LED and an acousted signal.
