LND712 geiger-müller detector tube


These are new (never used) and hard to find LND712 end window alpha beta gamma detectors. If you have ever wanted to build your own Geiger counter, this is the part for you!
Full specs of this detector can be viewed on LND's web page: http:// /products/348/
I built my own counter using one of these tubes and it works great. Please let me know if you have any questions.
I was told thit is the same tube used in the popular SE International Monitor 4 detector kit, so if yours is damaged, this would be the replacement.
