Geigger Muller Tube Holder SH059A

“Shipping from the UK & India”

Geiger-Müller tube holder, for use with GM tube and scaler timer. The unit consists of an Aluminium box 58 x 33mm (Ø x depth) which houses the GM tube socket. Connection is through a 1m long coaxial connecting lead, terminated in a standard TNC connector (replacing the obsolete PET connector featured in previous units). A 2.2MΩ stabilising resistor is internally wired in series with the anode connection.
This holder is compatible with radioactive timers which have a BNC Connector.
If schools have an older timer which does not have a BNC connector, these timer connectors can be updated and replaced to accommodate a BNC Connector.
