Geiger Counters; Digital, PC, Analog and Kits

Geiger Counters detect and measure radioactivity. There are three forms of energy associated with radioactivity; alpha, beta and gamma radiation. The classifications were originally determined according to the penetrating power of the radiation. All of our Geiger Counter can detect the three types of radiation; alpha, beta and gamma radiation and are sensitive enough to detect and measure background radiation. More information on Geiger Counters and Radiation may be found here.

Digital Geiger Counter with PC Output / NRC Calibration Certification Available

GCA-04

Images SI Inc's Digital Meter Geiger Counters are the most accurate in the world, easily exceeding the accuracy of analog and digital geiger counters costing twice as much. NRC calibration available, see our certification link below.

NRC Calibration and Certification Page

Our digital geiger counters, provide both a high accuracy count (CPS/CPM) and equivalent radiation level on the LCD display. U.S. government NRC Regulation 10-CFR-34 and 10-CFR-35 certifications are available. Many geiger counter features are listed on our page Digital Geiger Counter page (link below) including interactive interactive tutorials on the windows Geiger Counter program. Radioactive sources can be found on our Geiger Counter Accessories page.

Our Digital Geiger Counters are useful for detecting and measuring radioactivity and performing nuclear experiments. Wide ranging applications for industry, scientific and education.

Application include; classroom demonstrations and experiments, emergency services and domestic preparedness, HAZMAT and compliance verification, dirty bomb screening and EMT's.

Analog Meter Geiger Counters

GCA-03

Images SI Inc's Analog Meter Geiger Counters are useful for detecting and measuring radioactivity and performing nuclear experiments. It's applications include classroom demonstrations and experiments, emergency services and domestic preparedness, HAZMAT and compliance verification, dirty bomb screening and EMT's. Analog meter range is 0 to 20 mR/hr. These geiger counters also have secondary indicators; an audio click and LED blink each time a radioactive particle is detected.

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:

Digital Meter Adapter - Turns our analog into a accurate digital geiger counter
RS-232 PC Adapter - With free Windows Radiation Monitoring Software
Random Number Generator - Generate real random numbers for experiments

External Power Jack

Geiger Counters

GCK-02A

Analog Geiger Counters are useful for detecting radioactivity and performing nuclear experiments. These Geiger Counters primary indicators are an audio click and an LED blink each time a radioactive particle is detected. The Model GCK-02 has an internal Geiger-Mueller tube. The model GCK-01 (not shown) has an external wand that houses a Geiger-Mueller tube (GMT-01) and provides a easy to use probe for checking radioactivity.

The CGK-01A and GCK-02A 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:
