This is a very rare collection of Geiger counters. These counters from the former Soviet Union are no longer produced. They are in excellent condition and well-preserved.
They all come from a lab that was disbanded recently. Tested for tightness and working condition.
There will be no other opportunity to buy such a rare tube.
Original USSR name Latin letters Alt.
