| Applications and Uses | Personal Radiation Detector and Survey Meter: Domestic Preparedness: Education and Nuclear experiments: Emergency Services: Post-Accident Response. Compliance Verification and Radiation Screening for Wastes and other materials. |
| Proven Track Record | For detecting and measuring nuclear radiation in hospitals, medical research, college laboratories, industrial settings, transport containers, top soil, granite tables, scrap metal, oil fields, and interior spaces. |
| Fast, Accurate and Easy To Use | Detects a broad spectrum nuclear radiation, including low energy background radiation |
| American Made GM Tube | Assembled in the USA. USA Tech Support. |
| LCD Display | The 16 x 2 character LCD displays radioactive count and radiation level in mR/hr or mSv/hr. Time selection switch allows Counts Per Second (CPS) or Counts Per Minute (CPM) mode. |
| Case Size | The GCA-03W measures 5-3/4" (length) x 3-1/2" (width) x 1-1/4" (height). |
| External Probe | The external wand makes it easier to search materials and to detect surface contamination |
| Counting Range | 1 Count Per Minute (CPM) - 5000 Counts Per Second (CPS). |
| Radiation Range | 0.001 mR/hr resolution / 500 mR/hr Range (Imperial measurements); 0.01 uSv/hr resolution - 10 mSv/hr range (Metric). |
| Nist Traceable Calibration | Factory calibration using an NIST traceable radiation source to insure accurate radiation measurements. |
| Power | For mobile operation a 9V battery (not included) may be used. A 110-220 VAC wall transformer power supply is included. |
| Detects Lonizing Radiation | - Detects Beta radiation above 50 KeV
- X-Ray and Gamma radiation above 7 KeV.
|
| External Wand | Constructed using 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 Windows PC Geiger Counter Graphing program (not included) 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. |
| Power | For mobile operation a 9V battery (not included) may be used. A 110-220 VAC wall transformer power supply is included. |
