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 30 bend or optional 10 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
