The Philip Harris GM Probe offers teachers and students a reliable way to detect alpha, beta, and gamma radiation during science lessons. Designed for classroom use in secondary schools and colleges, it provides a practical and cost-effective alternative for general radioactive experiments.

• Detects alpha, beta, and gamma radiation
• BNC connector for easy mounting with retort stands and clamps
• Compatible with timers and counters needing an external anode resistor
• Operating voltage range: 450–650V; recommended supply voltage: 500V
• Window thickness: 1.5–2.0 mg cm^-2
• Operating temperature: -40 to +75°C; anode/cathode capacity: 3pF

For classroom use only; not suitable for annual Radioactive Source Testing.
