Geiger-Probes
HP-265 Pancake GM Probe
The most popular probe for general survey, radiation safety,
contamination checks and emergency response.
Uses a pancake style (wide window, better sensitivity) halogen
quenched Geiger-Mueller detector. Thin mica window allows
detection of
alpha, beta and gamma radiation.
Available with standard 30⁰
bend or optional 10⁰
bend.
· Thin Window (1.6 mg/cm²)
· Available with standard bend or slight bend for ease of use
· Designed for easy replacement of GM tube
· Protective Copper/Bronze Screen- 72% Open Area
GP-200 End Window GM Probe
A popular probe for general survey and radiation safety. Uses an end window halogen quenched Geiger-Mueller detector. Thin mica window allows detection of alpha, beta and gamma radiation. Helpful if probe needs to reach into places to big for the standard pancake probe.
