C8092 ^ Super Sensitive Alpha Beta Gamma Mica Window SBT-11A/CBT-11A Geiger Counter Assembled Unit - Plus, Free Unprocessed
Detailed Description
Our absolute most sensitive Geiger Counter uses the super sensitive SBT-11A/CBT-11A mica window tube. The tube was made in Russia, however the Geiger Counter Board was made and assembled in the U.S.A. The tube is super sensitive and retails for $45 to $75. It actually has multiple sections of detectors inside the housing! The board is specially shaped as shown to fit inside of a high quality enclosure (4" x 3") if you decide to cut & drill so the Geiger Counter will mount in it. We give you the unfinished case for free as a bonus. The circuit board is fully assembled, tested and connected to the tube (no soldering necessary).
Note: We test each tube and place a piece of transparent tape over tube window for protection of the mica window. Please peel off tape before using, however be careful not to touch the mica window as it is thin and can ruin the tube if it breaks. The background counts per minute (CPM) here in Phoenix is about 36. Operates on one 9V battery (not included).
