Geiger Counter Accessories

Turn your portable Geiger counter into a hands-free laboratory tool. Clear acrylic construction provides a stable base and keeps the display visible.

• Ideal for classrooms, physics labs and independent research.
• Keep your hands free to adjust sources and record measurements.
• BTS-07 fits GCA-07, GCA-07W and GCA-07W-DL.
• BTS-06 fits GCA-06, GCA-06W, GCA-03 and GCA-03W.

The DMAD combines a digital meter adapter, serial interface and random number generator in one expansion module for analog Geiger counters.

• Pulse range: 1 CPM–9,360 CPS.
• Radiation range: 1.0 µR/hr–655 mR/hr.
• Metric range: 0.01 µSv/hr–6.5 mSv/hr.
• Backlit 16-character × 2-line LCD.

DMAD-04A is assembled and tested. Requires an analog Geiger counter with pulse output, such as GCK-01, GCK-02, GCA-03 or equivalent. Shown with optional stand, not included. Kit information is available on the product page.

More information

GCW-01

A thin mica window GM tube detects alpha, beta and gamma radiation. Operating range: 450–600 V; recommended voltage: 500 V.

GCW-02

A glass GM tube detects beta and gamma radiation. Operating voltage: 400 V; anode resistor: 2.2 MΩ.

Each wand is approximately 0.85" in diameter and 5.75" long, with a 3-foot shielded cable and mini DIN plug.

Replacement wands: We recommend sending in your digital Geiger counter so the new wand can be calibrated specifically to your unit.

Friction-fit shields reduce radiation reaching the GM tube. Compatible exclusively with the GCW-01 wand.

• SHD-02 paper shield: blocks alpha radiation · $12.95.
• SHD-03 aluminum shield: attenuates beta radiation · $12.95.
• SHD-04 lead shield: attenuates gamma radiation · $12.95.
• SHD-05 complete set: paper, aluminum and lead · $36.95.

The wand base provides a stable platform for experiments. It measures 2" × 12" and has metric and imperial length markings.

The movable sled holds 1" diameter radioactive isotope discs. Holders are available for 1/8" and 1/4" thick discs.

• SIHB-01 holder and base: $18.95.
• BASE-01 wand base only: $15.00.
• ISO-01 isotope holder: $4.95.

More information

Thin mica window detects alpha, beta and gamma radiation. Operating range: 450–600 V; recommended voltage: 500 V. Recommended anode resistor: 10 MΩ. Gas filling: neon and halogen.

Dimensions: 0.36" (9.1 mm) wide × 1.6" (40 mm) long.

Export note: This product is restricted for export to foreign countries. Additional information may be required before shipping.

Electrical and mechanical specifications

The ADM counts TTL pulses from an analog Geiger counter and displays CPS, approximate radiation level and an analog field-strength indication.

• Power input: 8–12 VDC or 5 VDC.
• LCD backlight.
• Available as a kit or assembled.

The first line of its 8 × 2 LCD alternates each second between CPS and approximate radiation level. Imperial mR/hr is abbreviated to mR; metric mSv/hr to mS. The second line gives an analog indication from 1 CPS to 2,040 CPS.

Mounts the ADM meter in the round panel opening of a CDV715 meter. Made from approximately 1/8" thick black plastic.

Crookes’ spinthariscope allows users to observe alpha radiation. Place an alpha source near the rear screen and view small flashes through the front window.
