Images SI Inc's Analog Meter Geiger Counters are useful for detecting and measuring radioactivity and performing nuclear experiments.

The geiger counter has a digital output that provides a TTL logic pulse each time a radioactive particle is detected. Used to connected to various digital adapters and network software.

Applications:

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

The analog meter is calibrated in mR/hr that is useful for approximating radiation levels. There are three pre-set ranges:
Ranges

• 0-1 mR/hr (Range switch set to 1X)
• 0-10 mR/Hr (Range switch set to 10X)
• 0-100 mR/hr (Range switch set to 100X)

These geiger counters also have secondary indicators; an audio click and LED blink each time a radioactive particle is detected. Model GCA-03 has an internal Geiger-Mulluer (GM) tube.

The GM tube is Ne + Halogen filled with a .38” effective diameter mg/cm2 mica end window.

Detects the following radiation:

• Alpha above 3.0 MeV
• Beta above 50 KeV
• Gamma above 7 Ke

The CGA-03 and GCK-03W Geiger Counters have the following features:

Headphone / Analog Meter Jack

Digital Output -- Provides a TTL logic pulse each time a radioactive particle is detected. Used to connected to various digital adapters such as; Digital Meters, Random Number Generators, USB and RS-232 Adaptors, Graphic software and network software.

Digital Meter Adapter -- Turns our analog into a accurate digital geiger counter
Geiger Graph Software - Turn your Geiger Counter Setup into a Radiation Monitoring Station

Optional Belt Clip

These radiation shields friction fit on the open end of the Geiger Counter wand. Each shield helps to block radiation from reaching the internal GM tube inside the wand.

The shields are useful in performing nuclear tests and experiments.

The Screen shield is an open mesh nylon screen that allows all radiation including alpha to pass through. The paper shield blocks alpha radiation, while permitting beta and gamma radiation. The aluminum shield attenuates beta radiation and the lead shield attenuates gamma radiation.Shields may be purchased separately or in a set.
