9320.008 - Radioactivity meter
The RayDetector 4040 is a Geiger counter (radioactivity meter), different from similar analog types which are difficult to read. It's equipped with a digital display and the sensor is a Geiger-Muller halogen tube.
It is possible to get the radioactivity measurement in the following units: 
mRem/h, μSievert/h, cps or cpm.
When a ionogenic radiation, with sufficient energy, comes into contact with the Geiger Muller tube, a lightning indicator (red led on the right of the display) and a buzzer are activated.

Application fields
- Survey of personal exposure
- Verification of material of unknown origin
- Search of radioactive minerals
