20keV-7MeV Radiation Detector Beta Gamma X Detection Surface Pollution Meter For Radiation Dose
TESTECH 20keV-7MeV Radiation Detector Beta Gamma X Detection Surface Pollution Meter for Radiation Dose or Contamination
One-hand operation, multi-ray detection, reliable data storage.
RM-100 Surface Contamination Monitor uses an imported mica-window GM detector to simultaneously measure α, β, and γ rays (including low-energy gamma like I-125). It delivers accurate readings of radiation dose rate, count rate, and surface contamination activity in a portable, one-hand operable design. With adjustable alarms, 1500 data points storage, and optional long-pole measurement, it’s the ideal tool for reliable radiation safety monitoring.
