GM Tube & Holder

The IPC Irwin GM Tube & Holder has been designed to work directly with our Timer Scaler & Frequency Meter (IPC-3342-T) via its TNC connection. It can also be used with many other makes of Scaler units simply by purchasing one of our TNC to BNC adapters (IPC-6205-R). The GM Tube itself is contained in a robust case (holder) to provide added protection to the delicate tube. The case also provides the option of attaching a support rod (supplied) to the underneath, therefore allowing it to be connected to a retort stand. Electrical connection to the GM Tube is via a fixed 750mm coaxial cable to a TNC plug, also contained within the case is a high ohmic value (4M7) series resistor required by most Counter and Ratemeter (Scaler) units.
