This Digital Geiger Counter with External Wand is a highly accurate and NRC certification ready instrument. An NRC Certification (additional cost of $125 for this certificate) tells you the Geiger counter is as accurate as "accurate" can be. Your radiation reading reports are authoritative and acceptable to government agencies.

Product features
DETECTS AND MEASURES: Alpha, Beta, X-Ray, and Gamma radiation.
* NRC CERTIFICATION READY: NRC Certification can only be given by U.S. Government licensed laboratory. The NRC certificate certifies that the radiation reading from the Geiger counter is accurate.
* COUNTING RESOLUTION AND RANGE: 1 Count Per Minute (CPM) - 10,000 Counts Per Second (CPS)
* RADIATION RESOLUTION AND RANGE: 0.001 mR/hr resolution/1,000 mR/hr range (Imperial measurement); 0.01 uSv/hr resolution - 10 mSv/hr range (Metric)
* DETECTOR SENSITIVITY: Detects Alpha particles above 3 MeV in energy. GM tube has a thin mica window that allows alpha radiation to be detected. Beta radiation above 50 KeV; X-Ray and Gamma radiation above 7 KeV

EASY TO READ LCD SCREEN: With numeric display, intuitive function switches, software for printing out the results in a bar-graph format, low battery power indicator, and more.

MOBILE OPERATION: 9 Volt battery powered for mobile operation. A 110 VAC to 9V Wall transformer power supply is included.

Three Radiological Instruments in One

Survey Meter
Takes real time radiation readings and displays the count/second and equivalent radiation level in either mR/hr or mSv/hr. These are real time one second interval readings for count with three second averaging on radiation level. Count readings will fluctuate second by second, because it displays the actual number of radioactive particles detected in comparison to analog meter counters that average radioactivity levels.

Background Radiation Monitor
Take 1 minute or 5 minute readings. Displays accumulated count and equivalent background radiation in either uR/hr or uSv/hr.

Scientific Instrument & Industrial Tool
This Digital Geiger Counter is calibrated using CS-137 Gamma source and is NRC certified accurate in reading radiation levels to +/- 5%.

Perfectly suited for classroom demonstration, research, and experiments in school as well as industry use for HAZMAT and Emergency Services.

Comes with free Windows radiation graphing and recording programs. Graphic files may be exported to Excel spreadsheets.

Applications:
* Education - Classroom demonstrations and experiments
* Emergency Services and Domestic Preparedness
* HAZMAT and Compliance Verification
* Dirty Bomb Screening and EMT's

The high contrast Liquid Crystal Display (LCD), 16 character by 2 lines, provides an easy to read output.

Secondary indicators; audio (clicks) and visual (LED) included. Also includes a headphone jack and a power jack for external power.

This Digital Geiger Counter outputs serially via RS-232 the counts per second to the Windows PC program for charting and recording the measured radiation over time (see WIN XP screen shot). Saved graphic data files may be imported into Microsoft Excel.
