Velp Radiation Detector Cat. No. R10800340

Standard industrial model of a Geiger-Müller tube with a thin mica output window.

Accurate Operation

  • Factory-calibrated using a pulse generator
  • Standard ±15% of the full scale relative to Cesium-137
  • Results in milliroentgens/hour and counts/minute (cpm) in 3 periods
  • Anti-saturation circuit up to a value equivalent to 100 times the maximum reading in the greatest interval

Easy to Use

  • Results by graduated scale, flashing LED and acoustic signal
  • Operates up to 2000 hours on one set of batteries
  • Detects α, ß, γ and x-rays
  • Choice of 3 measurement ranges
