Replacing a Wand?
If you are purchasing a replacement wand for one of our digital Geiger counters, we recommend sending in your counter along with your order so our technicians can calibrate the new wand to your unit.
Compare Radiation Penetration
These radiation shields friction-fit onto the open end of the Geiger counter wand, helping reduce the radiation that reaches its internal GM tube.
Use them in nuclear experiments and educational demonstrations to compare readings with different shielding materials.
Compatible exclusively with the GCW-01 wand.
