DETECTS IONIZING RADIATION: The "c" models detect Beta radiation above 50 KeV; X-Ray and Gamma radiation above 7 KeV.
SENSOR The "c" models use a Tin Oxide Glass Coated Geiger Mueller (GM) Tube. The GM tube has a 0.433" (11mm) effective diameter.
LCD DISPLAY is a 16 character by 2 lines display. Displays count and equivalent radiation level.
CPS MODE: LCD displays second by second count and current radiation level in millirads (mR) per hour (mR/hr) Imperial or in millisivets (mS) per hour (mS/hr) Metric. Switch selectable.
CPM MODE: LCD display minute by minute count and background radiation level in microrads (uR) to millirads per hour (mR/hr) Imperial. Or in microsivets (uS) to millisivets per hour (mS/hr) Metric.
I/O OPTIONS: Headphones. External Speaker. External Power. 3.5mm Data Port for WIN PC and microcontroller interface. WIN PC requires optional 3.5mm to USB data cable.
DATA OUTPUT PORT: The 3.5MM stereo socket outputs either Serial Data (default) or a TTL logic pulse for each radioactive particle detected. Jumper switch selection. The serial output is the counts per second sent via USB cable (not included) to our Windows PC Geiger Counter Graphing program for charting and recording the measured radiation over time.
SECONDARY INDICATORS: Audio (clicks) and visual (LED) included. Also includes a headphone jack and a power jack for external power. A 110 VAC to 9V wall transformer power supply is included. 9V battery (mobile operation) not included.
