Geiger Counters

The Gamma-Scout is a general purpose geiger counter that measures alpha, beta, gamma and x-ray radiation. It has proven to be useful in the medical, nuclear, mining, metal scrap and foundry industries. It is also used by first responders, police, customs and border control, hobbyists, rock hounds and in personal or home survival kits. The Gamma-Scout sets a new standard in portable geiger counter performance and functionality.

Casing Impact-resistant Novadur
Display Real time LCD display, 4 digit numeric with operating mode indicators. Logarithmic bar chart.
Calibration Each unit is subjected to a final test supervised by the Institute of Radiation Protection, a government (German) controlled university for Applied Technology. The tested device must be in a confidence range of 5% in comparison to a master. This master is adjusted to a gauged reference Cs-137 emitter. Each unit gets a serialized test certificate.
Selective Shielding Shield the sensor's mica window from alpha (to allow beta and gamma only) or from alpha and beta (to allow gamma only).
Power Consumption Power circuit consumes less than 10 microamperes at environmental radiation.
Dose Rate Units Can be set to display units in Sievert or Rem
Cumulative Dose Can be set to sum up dose measurements to give the cumulative dose reading from some point in time.
Data Download Connects to Windows PC for a batch data download of archived data measurements in memory. Memory can be wiped clean for a fresh start of data archiving.
"Always On" Feature Monitors radiation continually for a comprehensive and accurate data archive in memory that is downloadable. The unit cannot be turned off.
Ticker and Programmable Alert Audible alert ticker can be turned on and clicks with each pulse generated by the GM tube in the presence of radiation. A programmable alert can be set to sound by the unit on crossing a dose rate threshold.
Embedded Battery Embedded (soldered on) Lithium Thionyl Chloride battery, with a typical 10 year operating life at average 20°C and normal usage. There is no need to recharge this battery through its lifetime. To replace send back to factory for a replacement for a small fee.
Rechargeable Battery Can be charged via USB cable or external power supply (included)
Real Time Data Download Connects to Windows PC and sends the data measurements (pulses) in intervals of 2 seconds
Certifications Meets all European CE standards as well as US FCC 15 standard
Warranty 2 Year Manufacturer's Warranty [does not cover damage to GM tube]
