Geiger Muller Tube Holder with PET-100 plug

Designed for safe and effective use in school science labs, this Geiger Muller Tube Holder is perfect for demonstrating alpha, beta and gamma radiation as part of the physics curriculum at KS4 and A-level.

Supplied with a 1 metre flying lead and standard PET-100 connector, it integrates seamlessly with most school counters and ratemeters. The high-efficiency ZP1481 GM tube features a large-area detection window, ideal for practical investigations and classroom demonstrations.

Built to operate at 440V, this unit complies with CLEAPSS guidance GL138, and includes a built-in 2M2 high-ohmic resistor to extend tube life and ensure compatibility with most detection systems. A removable protective grill covers the detection window, allowing for low-level contamination experiments when required.

The holder can also be mounted on a retort stand using the included fixing rod, providing flexibility and stability during use.
