(as of [price_update_date] – Details)

The GCA-03W Digital Geiger Counters are useful for detecting and accurately measuring radioactivity.

The GCA-03W Geiger counter has an external wand probe that houses a Geiger Mueller tube. The external wand makes it easier to search materials and surfaces for radioactivity.

This Geiger counter’s applications are: Education – Classroom demonstrations and nuclear experiments; Emergency Services and Domestic Preparedness for nuclear accidents. Compliance Verification and Radiation Screening for wastes and other materials. NIST calibration performed by independent laboratory that conforms to NRC regulations 10-CFR-34, 10-CFR-35 are available at additional costs through the manufacturer.

The Liquid Crystal Display is a 16 character by 2 line that provides an easy to read digital output. Switch selection allows GCA-03W Geiger Counter to measure and convert radiation (counts per second) into in mR/hr or mSv/hr. Time selection switch allows Counts Per Second (CPS) or Counts Per Minute (CPM) mode. All Geiger Counters are factory calibrated to insure an accurate measurement.

Data Output Jack: Outputs either Serial Data (default) or 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 (free download from company website) for charting and recording the measured radiation over time. Secondary indicators; audio (clicks) and visual (LED) included.
