IMAGES' DIGITAL GEIGER COUNTER are the only Geiger counters you will ever have to purchase. They have a proven track record detecting and measuring nuclear radiation in hospitals, medical research, college laboratories,industrial settings, transport containers, top soil, granite table tops, scrap metal, oil fields, objects and interior spaces.

APPLICATIONS and USES: Personal radiation detection: Survey meter: Education and nuclear experiments: Emergency Services: Domestic preparedness: Post-accident response. Compliance Verification and Radiation Screening for wastes and other materials.

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-07W, GCA-07, and GCA-07W-DL measure 7 ½" (length) x 4.1" (width) x 1 ¼" (height). The GCA-06W, GCA-06, GCA-03W and GCA-03 5 ¾" (length) x 3 ½" (width) x 1 ¼" (height). The DTG-01 measures 8 ¾" (length) x 6 ½" (width) x 2 ¾" (height).

INTERNAL/EXTERNAL PROBE: Choose between an external wand or internal sensor. All models ending in "W" have an external probe, while those without have an internal sensor. The DTG-01 is only available with an external wand.The external wand makes it easier to search materials and to detect surface contamination.

COUNTING RANGE: GCA-07 series, GCA-06 series,DTG-01 - 1 Count Per Minute (CPM) To 10,000 Counts Per Second (CPS).

GCA-03 series - 1 Count Per Minute (CPM) - 5000 Counts Per Second (CPS).

RADIATION RANGE: GCA-07 series, GCA-06 series,DTG-01 - 0.001 mR/hr resolution to 1000 mR/hr Range (Imperial Measurements); 0.01 uSv/hr resolution - 10 mSv/hr range (Metric Measurements).

GCA-03 series - 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 of handheld units a 9V battery (not included) may be used. A 110-220 VAC wall transformer power supply is included with all models except the GCA-03 series (sold separately).

RANDOM NUMBER GENERATOR: DTG-01 only - Range Selectable 1-2 and 1-128. TTL Serial output.
